x^2 - 4x -12 = 0
(x + 2) (x - 6) = 0
x + 2 = 0 or x - 6 = 0
x + 2 - 2 = 0 -2 or x - 6 + 6 = 0 + 6
x = -2 or x = 6

x2 - 4x - 32 = (x - 8)(x + 4)
6(x2 -4x - 12) 6(x-6)(x+2)
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
If that's -5 the answer is (x - 5)(x + 1)
f(x) = x2-4x-5 = x2-5x+x-5 = x(x-5)+1(x-5) = (x+1)(x-5) Factors of f(x) are (x+1) and (x-5).
