So, I have a workbook for my Calculus class, and its review of high school math with no calculator, its been fairly smooth sailing thanks to a question answered on here yesterday. Rather, it was pointed out that I was being a moron.

Now I have come back asking for help again.

I have the following question, and I don't need an answer, I'm just asking for somebody to show me what the heck I am supposed to do, please.

The question. (i'm going to try the math text)
