Question

Determine whether the polynomial (2x-3)(7x+21) is completely factored or not. If not, factor the polynomial.

A. completely factored
B. 3(2x-1)(x+7)
C. 7(2x-3)(x+3)
D. 7(2x-3)(x-3)

Answer 1

C

Explanation:

This form is almost fully factored. The expression (7x + 21) can factor to 7(x+3).

This means the expression can be factored to 7(2x-3)(x+3).
