Answer:

D) (x + 2)(x - 6)

Step-by-step explanation:

Rewrite the equation so you can factor some things out. This'll be x^2 + 2x - 6x - 12 (because 2x and -6x give you -4x). Now, factor it out to get

x(x + 2)-6x-12; x(x + 2) -6(x + 2). Factor out x+2 from the expression to get (x+2)(x-6). This is your answer.
