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!

Damn i wish i had a cool teacher like this guy

• April 15, 2017 at 5:06 am

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!!!!!!

• May 4, 2017 at 11:50 pm

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.

• May 5, 2017 at 4:28 am

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".

• May 8, 2017 at 6:38 pm

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

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

• August 14, 2017 at 3:45 pm

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.

• August 29, 2017 at 6:48 pm

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

• April 9, 2018 at 12:33 pm

This formula was created by ancient Indian mathematician Shreedharacharya.

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