    The numbers are 6 and 4

    Step-by-step explanation:

    Let x = integer

    The second is x-2

    Product of x * (x-2) is 24

    x (x-2) = 24

    Distribute

    x^2 - 2x = 24

    Subtract 24 from each side

    x^2 - 2x - 24 = 24-24

    x^2 - 2x-24 = 0

    Factor

    What two number multiply together to give 24 and add to - 2

    -6*4 = - 24

    -6+4 = - 2

    (x-6) (x+4) = 0

    Using the zero product property

    x-6 = 0 x+4 = 0

    x=6 x=-4

    The question states the number is positive

    x=6

    The second number is x-2 = 4

    The numbers are 6 and 4
