Could someone please explain how(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{x^2}{x^2+2}=1-\frac{2}{x^2+2}[/tex]

and how

[tex]xlnx-x=xln(x-1)[/tex]

Also, is there a list of types of simplifications like these two that I could study? I'm in Calc II and my own trouble comes from simple things like this that I should already know.
