    Just use the parametric equations and write out (x-y)(x + y)^2 and answer falls out

    I recommend also finding x-y for this question, which should make your method faster and lead to fewer mistakes.

    Post your attempt if you get stuck.

    EDIT : Since they give you the form of the solution ( I didn't notice that), it's quickest to follow the previous poster's advice.
