I was confused about what you were trying to ask, but I think that this work will explain it if I was right. Please let me know if you have any further questions, or if I didn't interpret the expressions correctly. My work is correct for the Question that I wrote. 

Just for the people in the future this is what my test said for the answers, hope it helps.
