I recently started college and I'm in the first Math class, College Algebra. I'm having some problems with simplifying some basic functions if anyone can help me out.(adsbygoogle = window.adsbygoogle || []).push({});

Problems like:

Example 1:x^-2 - y^-2 / x^-1 + y^-1

Example 2:x^-1 + y^-1 / (x+y)^-1

If you noticed, I seem to be having problems with the problems involving negative squares. Any help on how to work these problems is greatly appreciated.
