Quadratic Equations
Formula Method
x = [-b +/- (square root) b^-4ac] / 2a
(a + b)^ = a^ + 2ab + b^
(a - b)^ = a^ - 2ab + b^
(a + b)(a - b)= a^ - b^

E.g: x^+ 12x + 4
=(x + 6)^ - (6)^ + 4
Solve for x
(x + 6)^ - 32 = 0
(x + 6)^ = 32
x + 6 = (root square) +/- 32
x = (root square) +/- 32 - 6
= (x + 6)^ - 32
