Wait, rephrasing this question
Unless you want to factor the numerator over the reals, this is as simplified as it's going to get.
I don't see how this helps, so I'd leave it in the form you put it in.
In general you want to simplify the expression as much as you can. This is either for the sake of clarity or perhaps because you are going to use the expression later and you want to make it as "simple" as possible.

Thanks, Dan. I made a mistake in this thread which I had been dealing with for an hour but of course noticed as soon as I made a thread!
However, my original question is still valid and has been clarified at: Simplifying to get the correct answer
