    I guess that you are expected to use the difference of two squares result
    here:

    u^2-v^2=(u-v)(u+v).

    Here you have:

    x^4-(x-z)^4.

    Now use x^2 for u and (x-z)^2 for v, this will give you the first stage
    of factorisation. The difference of squares can then be applied again to further.
    factorise the expression.
