Lyrics:

Write the equation in standard form
Factor out the leading coefficient
Subtract the constant from both sides
Create a square using addition

Rewrite and complete the square
Use the square root to solve for “x”
Subtract out the discriminant
Rewrite it and you solved for “x”

X equals negative b
Plus or minus the square root
Of b squared minus 4 ac
All over 2a
(x2)
