Since x^2 has a coefficient of 1, this is a simpler factoring problem; look at the factors of 12 & see which pair add up to -8

1,12 ; sum is 13, nope
-1,-12; no
2,6; no
-2,-6; sum is -8, and this is what you are looking for

x^2 -8x + 12 = (x-2)(x-6)

x^2 - 8x + 12 = 0
x = [8 +- Sq Rt (64 - 48)]/2
x = (8 +- 4)/2
x = 6
x = 2
(x-6)(x-2) = x^2 -8x + 12
