Question

What is the factorization of the polynomial below?

2x^2 + 24x + 72
A. (x + 2)(x + 6)
B. (2x + 6)(x + 6)
C. (x + 6)(x + 12)
D. 2(x + 6)(x + 6)​

Answer 1

Answer: 2(x + 6)(x + 6)

Explanation:

D.

Answer 2

D

Explanation:

Begin factoring by removing a GCF.

The GCF is 2.

2x² + 24x + 72 = 2(x² + 12x + 36)

Two numbers which multiply to 36 and add to 12 are 6 and 6.

So it factors completely into 2 (x+6)(x+6).
