Factor the expression x2 − 4x − 12. a. (x − 6)(x − 2) b. (x − 6)(x + 2) c. (x − 4)(x − 3) d. (x − 4)(x + 3)

B.   (x - 6)(x + 2).

Step-by-step explanation:

x^2 - 4x - 12

We need 2 numbers whose product is the last number -12 and whose sum is the coefficient of x (-4).

These numbers are -6 and + 2.

So the factors are (x - 6)(x + 2).

I know its not up there. When I did that I got (x+6)(x-2)
