Quadratic Formula Song

A song about the quadratic formula. You can memorize the whole formula and also understand the proof.

Lyrics:

If you try to solve a quadratic equation,
I promise you: It's possible without any frustration,
if you take everything, move it to one side,
sort by x squared, x and the rest. Alright.
Take the coefficients, name them a, b and c
and if you know the right formula, you will see
that you get the solution in the very next step.
Just sing this song in your head:

Negative b plus or minus the square root of
b squared minus 4ac over 2a

Okay. Let's start with our equation and our job is going to be
solving this now for x, so let's take minus c,
multiply by 4a and if you now add b squared
it all looks way to complicated, but don't be scared.
Just take a close look to the left side and you'll see:
There's a binomial formula with 2ax and b,
so altogether this is the square of 2ax+b
and now we have only one x, so the next step will be
to get rid of the square and if the right side is not negative,
the square root must be one solution, but there's an alternative,
'cause minus the square root yields the same if you square it,
so we write "plus minus" and now we are at the point, where it
only takes two more steps to solve it for x
and if you look to the left side, you know what will be next:
Subtraction of b and division by 2a is giving us our formula for x. Okay. And it's

Negative b plus or minus the square root of
b squared minus 4ac over 2a

Chords:
Fm Db Ab Eb (and at the end: Gm Eb Bb F)

for guitar you can play with capo +1 or just a semitone down:
Em C G D (and at the end: F#m​ D A E)

Not only did he tell us the formula.... he derived it too... where has this been all my

My math teacher showed me this song 4 years ago. This was when I hated math. Now I'm an engineering student and still sing this song in my head to remember it when solving these tasks👌

When you want to become a musician but your parents want you to become a mathematician 😂😂😂🤣🤣

This guy : Hold my formula.

My math teacher has this on repeat for 40 minutes daily now. I'm going absolutely crazy.

Crush: I love maths.

My algebra teacher showed this to us last year, and thanks to that I will forever have the quadratic equation memorized. I’m not going to forget it even if I try

[hemasingh]

When I finish memorising the periodic table song I’ll move right onto this one 😭😂

[TehmasKhan]

Me: studying calculus late at night

YouTube: Wanna learn quadratic formula?

Me: hell yeah.

[lightningbolt]

Thank you for the explanation of how ax^2+bx+c=0 becomes the quadratic formula! My math teacher told us the formula but didn't explain how to get it, so this video helped me a lot because I like to understand the math instead of just memorizing formulas.

everybody's gangsta till your maths teacher sends you this

First person in the universe to ever use a quadratic formula out of class

Me: singing this song during exam
