You can put this solution on YOUR website!
i take it you mean... %28x%2By%29%5E3+%2B+125?

What do you want to do with it? Note that 125 is 5%5E3, so if you need to factorise the expression, you basically have a%5E3+%2B+b%5E3 which factorises to a recognisable set of factors. I just cannot remember them :-). It should be in your textbook though.
