Answer:A
Which of the following is equivalent to 2x2 - 6x - 8 ?
A. 2(x - 4)(x + 1) B. 3(x + 4)(x - 1) C. 2(x - 3)(x + 2) D. 3(x - 4)(x - 2)
Explanation: A This question requires factoring the expression 2x2 - 6x - 8. Begin by factoring 2 from the expression: 2(x2 - 3x - 4). This expression is further factorable, giving 2(x - 4)(x + 1), which is (A).
