Question

Factor completely 5ab(x + 6) − 4(x + 6).

A Prime
B (x + 6)(5ab + 4)
C (x + 6)(ab)
D (x + 6)(5ab − 4)

Answer 1

D (x + 6)(5ab − 4)

Explanation:

The two binomials in the parentheses are the same so we can rewrite this as

(x + 6)(5ab − 4). We cannot simplay factor (x+6) anymore and (5ab − 4).

Answer 2

the correct answer is D (x+6)(5ab-4)
