How can I use the Quotient Rule for derivatives to simplify my final result?

[Agent M27]

I am still working on getting anything other than subscripts to post with my latex formatting, so for now I have posted a word document. Any help would be greatly appreciated, thanks.

Multiply your final result by sqrt(x) over itself. That will probably do the trick for you.

Caveat: I quickly scanned your work and it looked OK, but might have missed something.
