    Step-by-step explanation:

    4x2 + 4x - 3

    Multiply 3 by 4 = 12 find factors of 12 then

    4x2 + 6x - 2x - 3

    2x (2x + 3) - 1 (2x + 3)

    So (2x + 3) and (2x - 1) are the factors

    f (x) = 4x^2 + 4x - 3

    f (x) = 4x^2 + 6x - 2x - 3

    f (x) = 2x (2x + 3) - 1 (2x + 3)

    A. f (x) = (2x + 3) (2x - 1)
