Hey guys, taking Calc 1 and having some issues solving something that's likely very easy. As you can see in the attachments, I'm working on difference quotients. It wants me to simplify and rationalize. I know I can rationalize this (although I don't really understand why I would want to since we usually rationalize the denominator), but I can't seem to simplify it anymore. Maybe I'm just forgetting some of the rules of square roots?
Anyway, any help would be appreciated! Thanks in advance for your time
