You never stated if the square and the cube were of the same number. If the number is, say “x”, in both cases, then you have x^3 - x^2, or x^2(x-1).

If the numbers in question are different, then you have something like x^3 - y^2, which is as far as you can take it without knowing the values of x and y.
