C)(3x - 4)(4x + 3)
D)prime

Question

Quizplus · Accepted Answer

The correct answer is (A) (3x + 4)(4x - 3) because the product of the first coefficients (12) and the last constant (-12) is -144. The middle coefficient (7) can be factored into -9 and 16, which add up to 7 and multiply to -144. Therefore, the factors are (3x + 4) and (4x - 3).
