    then you Simplify 2x2+4x - 2

    Pull out like factors : 2x2 + 4x - 2 = 2 • (x2 + 2x - 1)

    Factoring x2 + 2x - 1 so then its coefficient is 1 .

    then the middle term is, +2x so its coefficient is 2 .

    The last term, the constant, is -1

    then we multiply

    1 • -1 = -1

    then we find two factors of -1 whose sum equals the coefficient of the middle term, which is 2 .

    -1 + 1 = 0
