You can put this solution on YOUR website!
ok, with questions like this, we can be fairly certain that it factorises, so keep calm and build it up slowly...

+x%5E2%2Bx-yx-y+ --> look at the first 2 terms and then seperately at the last 2 terms and we can write it as:

x(x+1)-y(x+1)

We still have 2 terms, now seperated by the - sign, so we can look at these 2 terms and see what is still common, to pull that out. Common term is (x+1), so we can now write it as:

(x+1)(x-y)

and this is your answer, now factorised :-)
