    A) 4x^4 - 4x^3 - 16x^2 + 16x

    B) 4x^4 + 4x^3 - 16x^2 - 8x + 16

    Step-by-step explanation:

    A) (4x^2 - 4x) (x^2 - 4)

    we apply distributive property:

    4x^2 * x^2 - 4x^2 * 4 - 4x * x^2 + 4x * 4

    so we have:

    4x^4 - 16x^2 - 4x^3 + 16x

    4x^4 - 4x^3 - 16x^2 + 16x

    B) (x^2+x-2) (4x^2-8)

    we apply distributive property:

    x^2 * 4x^2 - x^2 * 8 + x * 4x^2 - x * 8 - 2 * 4x^2 + 2*8

    we have:

    4x^4 - 8x^2 + 4x^3 - 8x - 8x^2 + 16

    4x^4 + 4x^3 - 16x^2 - 8x + 16
