Question from Charles, a student:

I need some serious help solving this problem.

I need to find the derivative fo the following function.
\/ ______________
 \/ (x - 1) / (x + 2)    + 1

Hi Charles. I think this is what you are looking to find:

This simply requires using the chain rule a few times. The Chain Rule is really good for disassembling a complex derivative. I'll show you how this one is done and you can do the algebraic simplification:

Complete and simplify.

Hope this helps,
