    As I can't see a way to simplify this (unless you want to do a division problem) then I would factor first.

    No, now you have the problem in a form where you have a common x + 5 in the numerator and denominator. NOW divide. But remember that you can't divide by 0, so at the end you must write the line x \neq -5.
