This is my first attempt to ask for help on here. I'm not in school (52 years old) but just exploring. This is a problem from an old Lial text from 2001.

I have worked on this problem for almost an hour now and just need some resolution. I have four pages of notes here. I have tried all kinds of substitutions and can't get a way to connect the two sides. It's number 48 on page 200 for those who have it. Can someone give me a clue for how to solve this?

Thanks.
