Answer:

A

Step-by-step explanation:

What we need to do is to factor this equation.

When you factor, your two values need to add up to the number before x, and multiply to the last number or -12 in this case.

So the two values that add up to 1 and multiply to -12 are -3 and 4.

So the factored form of this would be

(x-3)(x+4)

To find the zeroes, we set both of these equal to zero.

x-3=0

x=3

and

x+4=0

x=-4

Therefore, the answer would be A.
