    2*^2+2x-12

    Step-by-step explanation:

    Use FOIL (First outer inner last)

    First

    x * 2x = 2x^2

    outer

    -4 * x = - 4x

    inner

    2x * 3 = 6x

    last

    3 * - 4 = - 12

    combine like terms

    6x-4x or - 4x*6x = 2x

    therefore your answer is

    2x^2 + 2x - 12
