Question: How to make maple show what I want it to?

Hey!

I am trying to simplify this: (a+b)(a-b). As we all know, this is a2-b2. Maple, though, returns this: a(a+b) - b(a+b) which is also correct, but not what I want it to show :D Any way to make it show a2-b2?

I tried simplify, factor, expand - they all give the same result. Am I doing it wrong? :D

Thanks in advance
