The first thing about the Quadratic Formula

is what we are actually doing, the first thing part is how do we find the quadratic function

a x squared plus b x plus c we have a quadratic function set equal to zero we’re using the

quadratic function negative b plus or minus the square root b squared minus 4 a c all

over 2 a to find where the function crosses the x-axis or when the function is equal to

zero so there is a tune that pretty much everyone knows by One Direction that we will use for

to memorize this formula you are welcome to sing along if you know the tune get out get

out get out of my head fall into my arms instead i don’t i don’t know what it is but I need

that one thing, you got that one thing! good so if you use that same chorus we can sing

the quadratic formula that is right here behind me negative b plus or minus the square root

of b squared minus 4 a c all over 2 a now you know the quadratic formula now you know

the quadratic formula so that is how it goes lets do it one more time just so you have

it down and i hope you enjoyed it negative b plus or minus the square root of b squared

minus 4 a c all over 2 a now you know the quadratic formula, now you know the quadratic

formula thank you for Watching!

OMG THIS IS AMAZING!!!! THANKS SO MUCH!!!!! I have to learn it tomorrow for math and I was not sure how to do it. because this is way easier to remember the pop goes the weisel lol!!!!!

you rock dude

Free Kodak

Love using your videos to help my students that I tutor!

we watched this in class today and I'm sure i'll always remember it with that tune becaise I love 1D

the kids catch on to the song pretty fast

My eighth grade teacher showed me this and this is the only reason I remember it

Is that for primary school pupils?

Dammit. I wish I have a math teacher like that.

I thought it was opposite b not negative b. Hmmm idk. Great video though ππ»ππ»ππ»ππ»ππ»

what the fuck is this I do method and dropped out

works really well and got me though the question on my exam. Iv'e learnt it before but never with a song and the song really fitted the quadratic formula .Wish every school did that because it works really well and definitely helps me remember it

HEY I KNOW U. U ARE THAT DUMB ASS TEACHER WHO SUCKED MY

dumbass teachers

get a life.

#bestcommentsevermadebyme

why are they singing

If I had this teacher, I would want to learn math everyday.

Damn i wish i had a cool teacher like this guy

no hatred or anything loved this video but one thing thats wrong here guys can totally mess someone up…the part where he said negetive b….its not negetive b thats not how it should be stated instead its should be said as opposite of b….theres a huge difference between negetive of number and opposite of a number …but this was very helpful!!!!!!

lol 1 direction has gone downhill omg. He doesnt even look hot anymore. I used to have a waifu of him but now he looks like a middle aged teacher trying to teach meth lmao. Stop the madness.

If I ever become a math teacher I'm just gonna like show up to a class wearing a guitar but I won't play it for the entire lesson. Just so that people will be like "Why are you wearing a guitar".

Ever heard about DorFuchs? He is from Germany and does songs similar to this one. Here is a link to his first englich video. π

Hey, that's pretty good.

my favorite thing

YAYYYYYYYYY ONE DIRECTION

This saved my algebra grade

Lol the memes above the board xD

Awesome to see a teacher who goes the extra mile to inspire and grow his students

End would have been better if you sang "Know you know quadratic formulae". But nice song!

1:51 is when he sings the song ( note to future self when i'm tryna watch this QUICK in the line for my gcses lol )

excellent! !!

Bruh come to my school and teach me some maths you're amazing.

I really liked your video, but it would have been even better if you had proved the quadratic formula and showed us the simplified version as well, as it's done in this video.

https://youtu.be/USFvtyL5Ryw Nice video anyway.

i wonder.. purpose of this video was educational or entertainment.

just saying the plural of formula rhymes withe 'A'

Hate maths- love one direction πβ€οΈ now kinda donβt mind maths

Pathetic

them memes above the whiteboard, my math teacher needs to be like this

Why canβt he be my teacher

So clever!

Why canΒ΄t this guy be my teacher. Our teacher doesnΒ΄t know anything about Math.

Wow! I wish you were my math teacher! I actually learned something lol! But great job your an awesome singer!

so cute i like itπππππππ

Itβs funny because they give the equation in the new exam

Very helpful video on the quadratic formula! I also made this fun song about the quadratic formula which you may enjoy! https://www.youtube.com/watch?v=IfpkQVyqK7c

This is amazing ππ»

STOP OMG!! lol

Gimp.

1:18

Quadratic formula song of dorfuchs is better

Lmk how Iβm belting to this

why does everyone say βall over twoβ instead of βdivided by twoβ

This formula was created by ancient Indian mathematician Shreedharacharya.

Thus it's safe to assume that all Indians know it by heart. π

God, you Americans are weird.

Oh

such a cool teacher.

ONE DIRECTION ITS LIT!!!!1!!!

for some reason I can never remember this but now.. the game has changed

What has my life become

stick to teaching

Awwww my British boys

Wow all my math teacher does is yell at us when we ask a question because weβre βwasting class timeβ.

Memes on his wall, plays guitar and does this shit? And why isnβt he my teacher wow

he can actually play the guitar…?

My teacher actually showed this

I wish my teachers were like this

Isn't the square root of b squared just b? Does it mean square root of the b then square the answer or is it saying find b squared then square root it, I'm only 11 so pls don't get mad at me

as soon as I saw the memes on the wall I was like yeah this guys is different

This taught me more than Iβve learned in maths this year

What song is this based odd

Off

Great formula. 10/10 would use again.

i need teacher look like him π so creative

Really needed this guy 5 years ago

Cute ang mga Taga LS207 wiieeeeee

IS THAT FRANK FROM HOW TO GET. AWAY WITH MURDERR ππππ

https://youtu.be/106XiY9pVT4

You should get fired!

Iβm from Britain what grade do you learn this in

What are the chords and strumming patterns to this? I have to learn this for my algebra class now.

Just saw one direction and clicked…

This is great! Here's another awesome Quadratic Formula song: https://soundcloud.com/ben-fogg/quadratic-formula-song

This is the coolest way of teaching formulas… Loved it… π

Nice

I wish he was my math teacher

ONE DIRECTION IS THE BEST WAY TO HELP ME LEARN MATH LOL WHERE CAN I GET ME A TEACHER LIKE THAT LOL but actually my math teacher is lit he plays awesome music too

Quaaaddddd…..raaattttticccccc…..eqqqqqqqqqq ttttt^nnn

I put it in a sooooonnnnnngggggggggg….

HA! Math memes on whiteboard, LOVE IT!

Does this meme I'm a Mormon?

Im the 300th comment.

Negative B plus or minus

The square root of B square minus 4 A C

Over 2 A

Now you know the quadratic formula

Now you know the quadratic formula π΅πΆ

Good sir

I wish you. Are my maths teacher…π―

I wish he wuz my math teacher

Guess who sang that song in the head the day before yesterday at the math testππ

So, I started taking Algebra 2, and we had to learn this. Everytime we have to do something with it, I think of this song, and it helps

cubic formula has entered the chatomg thanks for this! i wish my teacher was like this!

Iβm here for the 1D song

Thanku so much ur video helped me so muchhh
