    22 and 24

    Step-by-step explanation:

    You can label the two consecutive positive integers as x and (x+2).

    So, we know their product is: x * (x + 2) = 528

    Here we simply solve this equation.

    xx + 2x = 528

    xx + 2x - 528 = 0

    x = - 1 + root (4 - 4 * (-528)) / 2

    x = - 1 + 46/2

    x = - 1 + 23

    x = 22

    and the other is 24

    22,24

    Step-by-step explanation:

    (x) (x+2) = 528

    x^2+2x=528

    x^2+2x-528=0

    (x+24) (x-22)

    x=-24,22

    Can't be negative

    22+2=24

    22,24
