Intro
2x Am F C G
[Verse 1]
Am F
If you try to solve a quadratic equation,
C G
I promise you: It's possible without any frustration,
Am F
if you take everything, move it to one side,
C G
sort by x squared, x and the rest. Alright.
Am F
Take the coefficients, name them a, b and c
C G
and if you know the right formula, you will see
Am F
that you get the solution in the very next step.
C G
Just sing this song in your head:
[Chorus]
Am F C G
Negative b plus or minus the square root of
Am F C G
b squared minus 4ac over 2a
[Verse 2]
Am F
Okay. Let's start with our equation and our job is going to be
C G
solving this now for x, so let's take minus c,
Am F
multiply by 4a and if you now add b squared
C G
it all looks way to complicated, but don't be scared.
Am F
Just take a close look to the left side and you'll see:
C G
There's a binomial formula with 2ax and b,
Am F
so altogether this is the square of 2ax+b
C G
and now we have only one x, so the next step will be
Am F
to get rid of the square and if the right side is not negative,
C G
the square root must be one solution, but there's an alternative,
Am F
'cause minus the square root yields the same if you square it,
C G
so we write "plus minus" and now we are at the point, where it
Am F
only takes two more steps to solve it for x
C G
and if you look to the left side, you know what will be next:
Am F C G
Subtraction of b and division by 2a is giving us our formula for x. Okay. And it's
[Chorus]
Am F C G
Negative b plus or minus the square root of
Am F C G
b squared minus 4ac over 2a
Am F C G
Negative b plus or minus the square root of
Am F C G
b squared minus 4ac over 2a
Bm G D A
Negative b plus or minus the square root of
Bm G D A
b squared minus 4ac over 2a
Bm G D A
Negative b plus or minus the square root of
Bm G D A
b squared minus 4ac over 2a
