We’re going to do more on factoring trinomials

and solving them Are you ready class?! (students: YEAH!)

Yay Math? (students: Yay Math!) When I say “Math” you say “yay”! Math!

(students: Yay!) Math!

(students: Yay!) When I say “yay” you say “math”! Yay!

(students: Math!) Yay!

(students: Math!) In case anyone at home is wondering,

this is my student’s jacket So I don’t blend in with the back Now I’m a floating head Now I’m not, okay (student: You are scary!) Do I look okay? Yay Math! Alright, we’re disrupting another class, sshh Question already, love it (student: What is a trinomial?)

What is a trinomial, good Trinomial is a polynomial, which is an equation With three terms One, two, three

(student: And then a polynomial is…) Is a many term equation (student: So a trinomial is a type of polynomial?)

A trinomial is a type of polynomial, excellent And we just heard someone said “I’m taking notes”,

That’s fantastic (student: That was me)

That’s great, I’m happy you said that So, first things first,

is there a greatest common factor? (student: Ah… no)

No There is no greatest common factor,

So we can start our factoring process If we were to do the ‘FOILing’ process;

what times what is 7x²? So what times what is 7x²? (student: Could it be 7x and then x?)

7x and x, is that clear? So we’re starting with that one,

now we’re going to go to this one What times what is 4? What do you think?

(student: 2*2 or 4*1) What do you want to start with?

(student: Let’s try 2 and 2) So let’s FOIL this, dude

(*caption note* First Outer Inner Last) I we were to FOIL to check,

forget about the signs for now Even though we can tell it will be both positive So, 7x², right? 7x*2 is?

(student: 14x) 2x, 4

Can these somehow add to make 29? (students: No)

No, so is it 2 and 2? (students: No) Let’s try 4 and 1, it’s like a game show Where do you want to put the 4? What do you think,

can you tell where you want to put the four? (student: In that one, the second one)

The second one Interesting that you should say that Could you put it in your own words

why it’s good to put the 4 here, and not here? (student: Because, umm… OH!)

OH! I love that moment! OH! (student: In the ‘O[uter],L[ast]’

you have to do 4*7x which would be 28x) (student: And then plus the 1x, oh) Exactly Where you going to say that, the ‘O’ sayer? Was that your intention? (student: Yeah, it was) Alright, so let’s make them plus, plus FOIL to check 7x², 28x [+] x, makes 29x, and 4. Yes? (student: The reason why you put

the 4 in the second parenthesis… …is because it’s bigger, and so it multiplies…)

With the 7 It will multiply with the 7 and that will make 28

and all we need is one more to make 29 (student: If you had put it in the first parenthesis then it wouldn’t be multiplied with the 7) Right, if you put the 4 here, 4 would be multiplied by x

and 1 would be multiplied by 7x so that would make 11x I’ll take the elevator Yeah, go ahead No, it depends on what the middle term is This elevator is broken So you put the bigger number wherever

you need to put the bigger number You’re still laughing, that’s awesome How many factors are still here? Two factors? So two factors, you set each to 0 to solve Because anything times 0, is 0 So we’re going to set the first factor which is

7x + 1 (student: Wait, I have a question)

Yes, yes, question? (student: That’s not the answer?)

No, the answer is solve for x, we have an ‘equals’ We need to solve for x This is factored, but we’re not done, solve! So, we set each factor to 0 x + 4=0,

I think everyone is writing, they don’t see that Everyone is writing, and when they look up, “oh” So now we solve, here we go! Minus 1 7x equals -1, divide by 7 *student sneezes*

Bless youuu! x=-1/7 *kids laugh* So high pitched I’m 1/16th mouse! In other words; great, great, great grandfather So these are the two answers.

Any questions? We solve both factors, set to 0 Alright, we’re going to do three more, you ready? Ready, Yay Math?

(students: Yay Math!) Please don’t do that Do you have the giggles? Do you really? (*student laughing*: I can’t breath)

That’s awesome Ladies and gentlemen, we have the giggles!

2m^3 -4m^2+50m can be simplified by 2

2(m^3 -2m^2 +25m) how do you distribute the m^3?

yep learned more in this 7 min video than in my 45 min math class

I've been stuck on a similar problem for so long! Thank you!!!! You made it so easy to understand.

Watching this right before my finals 😅

Solve, … Dude.

drake nigga lookin ass

Good explanation is it not support to be positive 4 or is -4

You are to math as Seinfeld is to humor!

As a 40 yr old, returning to college, wanting to refresh on what's needed for an upcoming Alg.2/Trig. course, you're helping in a big way!

why I hate math 🙁

I don't know how to be so yay about math. I barely understand how to do this stuff. I really don't think that we should use letters like y and z in math when it is mostly about using numbers. Also, I don't think that I will ever use this kind of Math in my life.

its funny how there isnt one male voice…

"I'm one sixteenth mouse!" 😂 That's my favorite thing you've ever said lol

your awesome

I wish our math subject was this happy ):

Our math teacher is so strict, coz she doesn't want her attitude to be taken for granted

this teacher pulls

Nice hairline…😂😂😂

Amazing teacher!

my teacher doesn't explain things so that the class can understand it. most of us are failing right now because we just don't get it. this video was a huge help. so yeah… thanks

Thankyou so much! My teacher thought i was smart enough to do extension work and so I had no idea how to solve these things until this video!

I just learned how to solve my homework problems from the help of your teaching style.

I'd kill my self if I was in this class

Wow, thank you! I've never seen it done this way, and it is so incredibly helpful.

ugh why are they so excited about math.

you were so interesting, I watched you for 5 minutes before I realized you weren't teaching the chapter I was curious about.

cringe

I wish I had you as my teacher

Boy u saved me lol

"LETS FOIL THIS DUDE"

why cant u be my math teacher

it's sad I've learned more from this than the 3 months we've been studying it keep it up

I'm still waiting for the day I have to use math in life

2:15 long ads before your videos is absurd.

dude u have no frickin idea how much this helped my math teacher sucks i finally get this bs

Coolest teacher EVER!

God Bless You Sir and God Bless the United Channels of Youtube.

I wish I had a teacher like this

found an easier way to do this on a ti84…

https://sourceforge.net/projects/dougtrinom/

why is everybody needing help when they are in college i am a freshman and i am learning this

you explain things so well and my 8th grade math teacher was great.

Fooo I been watching you and I can no understand you

How do I do 4a^2+4a+1? If I try to factorise it I just can't get the right answer

Dude, so glad I found this video. Working a full time job(night shift) and going to school almost immediately afterwards makes it so hard to understand what's going on. Feels great being able to say "oh, now I get it!" Keep doing what you're doing!

Hello, good video, you explain things well. I really want to see how you solve the last equation before the clip cuts off, where exactly is it on your website? I can't find it. 🙂

Probably would've enjoyed math if I had this dude

Alv no entiendo

0:32 wow u perv

as someone who grew up with terrible math teachers all through school, i have to say, i appreciate your way of teaching. you're one hell of a teacher. im doing this in my college algebra class and your the only one who has ever explained it in a way that actually makes sense. Thank you.

well done sir 👏

Awesome teacher, problem is, a majority of teachers lack enthusiasmif u would would be my maths teacher i would be happiest person in world and score 90 in maths

Can you please tell me why quadratic equation equal to zero

I WANT YOU AS MY TEACHER OH MY GOSH

How do you keep your students engaged?

thank you thank thank you!

Thank you o m g I forgot how to factor and was panicking.

thank u yay math i didn't want to study but with u i want to study every day i wish u were my math teacher for ever bec. my whole class hate our math teacher so love u and keep it up :):);)

Couldnt you just do the ac method

my teacher this process in less than a minute and it’s too fast for me, but this was great

looks like such a fun class!! so many questions being asked, i see many successful students and teachers in this vid

Your awesome at teaching! I wish I had you as a teacher in real life. I just realized this, math teachers are always my favorite teachers! They are always enthusiastic and nice! I have a question, where does the yaymath teacher teach? I hope it's in Maryland!

I don't understand nothing lol

This dude inspires me to be a teacher and I never considered it as a career.

Hé made it so easy 2 understand !

Anyone else still watching this in high school lmaoo my teacher blows.

My maths teacher in a nutshell: talks about Lamborghini (he doesn't own one)

2. Talks about his home country

3. Talks about snooker for whole lesson

6:04 Boy did he hit the right note

oh my god finally a video that makes sense

Math is so fucked up. In this example I couldn't use the AC method. So it works for only some examples. The same way as this method the teacher used in class. Super fail. Hate math.

You are an amazing teacher students tend to learn based on how their teachers act, many students are scared to ask questions because they might be embarrassed but you are just so chill and fun all your students are comfortable around you and you tend to actually make math fun, you are the first teacher i seen to actually make me and other students enjoy math, i actually enjoyed watching this video and also laughed a bit while learning a ton because you had made it fun to learn, we need more teachers like you

SI MATIMATIKA! dang this is old

You seriously are my dream guy., im sad to see this vid is 10 years old lol

This video is about 10 years ago and X is still not solving his own problem :/

I want him to be my teacher in math

I need this T E A C H E R

Sir please give me as my Bellow answer..

(X^15 + 1)÷(x-1)

School this friendly is wonderful let me transfer o_o to this school.

thank you so much, now I can do these lighting fast.

I'm so sick of these Study Pug ads. Like if you agree 9-9

Wow what a fun guy!

OMG thank you SO MUCH I finally understand it ;-; Thank you

first day of trig..jeeez

My math class is dead ass silent 💀 but I'm in ib math studies now and that shit hard

What city is this in

He is a fucking god.This dude aint bored anyone

Finally I understand this shit

I’m in 11th grade and I was literally struggling with it, THANK YOU SO MUCH. You’re such a good teacher.

nice x

I’m amazed your class is enjoying your class that much

An actual life saver. Thank you🙏🏾

Wow this guy is legendary. What a great example of a teacher

Study pug

6:17

I still don't know shit

I wanna be in this math class

Here's my 18 year old dumb ass in college tryna learn this shit before a test

So when the trinomial equals zero, you factor the same way you would if it didn't?

That's a revolutionizing sneeze

I have a test tomorrow. Trying to understand this fu**ing shit. And this man in messing around!

Man this was published 11 years ago…..
