Question

Which of the following is the correct factorization of this trinomial?

4x^2-0x-9
A. (4x-3)(x+3)
B. (4x-9)(x + 1)
C. (2x-3)(2x+3)
D. (2x - 9) (2x + 1)

Answer 1

(2x-3)(2x+3)

Explanation:

4x^2-0x-9

(4x^2-9)

(2x)^2 - (3)^2

We recognize that this is the difference of squares a^2 - b^2 = (a-b)(a+b)

(2x-3)(2x+3)
