Question

Factor the polynomial 2x(x-3)+9(x-3)

a)18x(x-3)
b)(2x+3)(x-9)
c)(x-3)(2x-9)
d)(x-3)(2x+9)

Answer 1

D.(x-3)(2x+9)

Explanation:

Answer 2

D

Explanation:

This polynomial is being factored using grouping 2x(x-3)+9(x-3). Factoring by grouping is complete when the terms inside the parenthesis match.

Then the factors are the GCF pulled outside of each parenthesis and one parenthesis factor.

(2x+9)(x-3)
