Undergrad Is There a Simpler Way to Understand Mathematics?

I am sorry but i am not a mathematician
Could this be simplified ?

A bit.

sorry but the link isn't working

You forgot a pair of parentheses: http://www.wolframalpha.com/input/?i=x^2+/+(y+(sqrt(x^2+y^2)-y))

To the OP: depends on what you mean by "simplified." What WolframAlpha gives is
$$
\frac{\sqrt{x^2 + y^2} + y}{y}
$$
which I would further simplify to
$$
\frac{\sqrt{x^2 + y^2}}{y}+1
$$

... or even one more step:
$$
\dfrac{\sqrt{x^2+y^2}}{y}+1=1+\sqrt{\left(\dfrac{x}{y}\right)^2+1}
$$
which gives a nice form with only one variable expression $z:=\dfrac{x}{y}$.

Links don't work for me either.
