    (x-y)^2(x+y) when simplified.

    yes, but i need to see the steps to understand it

    you need to look for common factors the first 2 terms = x^2(x - y)

    and -xy^2 + y^3 = -y^2(x - y)

    bring these together we get x^2(x - y) - y^2(x - y) do you follow this so far?

    do you get (x+y)(x-y)(x-y)?

    ok so notive that (x-y) is common so we have (x - y) ( x^2 - y^2) now the second parentheses can be factored further (its difference of 2 squares) finally its (x - y)(x - y)(x + y) or (x - y)^2 (x + y)
