    A + 2b

    Since, information is needed regarding the product, we must only consider 2b.

    the answer of a multiplication equation is called product.

    The sign of the product depends on the sign of b.

    b = 2 so 2*2 = 4. the sign of four depends on whether b is positive or negative.

    If b is positive then, 2 * 2 = 4; product is positive

    if b is negative then, 2 * - 2 = - 4; product is negative

    the sign of a has no bearing on the sign of the product of 2b.
