I am having trouble answering this question:

"Using evaluate *limit as x approaches 0* "

My main problem, I think, is getting rid of the x on the bottom, I do not know how to go about doing it.

My solution so far:

note:*the "limit as x approaches 0" I don't know how to input on latex, so pretend it is there before all these.*

Don't know what to do from here. I know the answer is zero, but I do not know how to get there from what I have. Help please.
