Answer:

      3ab(b-a)

Step-by-step explanation:

    Formula: (a-b)^3     = a^3-3ba^2+3ab^2-b^3

                    (a^3-b^3) = (a-b)(a^2+ab+b^2)

   solution:

       (a-b)^3-(a^3-b^3) = a^3-3ba^2+3ab^2-b^3-[(a-b)(a^2+ab+b^2)]

                                   = a^3-3ba^2+3ab^2-b^3-a^3-ba^2-ab^2+ba^2+ab^2+b^3

                                   = 3ab^2-3ba^2

                                   = 3ab(b-a)
