    3x³ - 12x

    3x (x²) - 3x (4)

    3x (x² - 4)

    3x (x² + 2x - 2x - 4)

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

    So 3x^3-12x

    factor out the 3x in both

    3x^3-12x = (3x) (x^2) - (3x) (4)

    reverse distribute

    (3x) (x^2-4)

    x^2-4

    difference of 2 perfect squares which is

    z^2-t^2 = (z-t) (z+t) so

    x^2-2^2 = (x-2) (x+2)

    the factored out form is (3x) (x-2) (x+2)
