I don't think you needed to reduce 4 to "(2)(2)," but that's right for the most part. You did forget the $\displaystyle \sqrt{xy}$ in the numerator, though.
Have you talked about absolute values yet in class? If so, think of how $\displaystyle \sqrt{x^2}$ isn't exactly the same as $\displaystyle x$. If you haven't gotten that far yet in your class, never mind; you did it just fine.
