You mean this?

(choice #1)

or this?

(choice #2)

(BTW, learn LaTeX, and you too can type math symbols/expressions/equations )

I'm going to assume you meant choice #1. Start by factoring out an x in the denominator:

Cancel the x's:

Multiply by y^3/y^3:

I don't think you can simplify further (correct me if I am wrong).

If you meant choice #2, I'll let someone else work it out.
