Answer:

B. (-2, -6)

Step-by-step explanation:

The constant term is the product of the values in the solution set. (Both A and B give 2·6 = 12.)

The coefficient of the x term (8) is the opposite of the sum of the values in the solution set. That is, the solutions add up to -8.

... A: 2+6 = 8 ≠ -8 . . . . not the solution set

... B: -2 +(-6) = -8 . . . . these values are the solution set.

The solution set is (-2, -6).
