As an example: (xsqr-2xy+ysqr)/x-y.
I am not sure how to superscript on this site, so I am using sqr to represent a squared varfiable.
If someone can remind me of the basic method, I think I will remember it pretty quickly!

Original expression:
$\displaystyle \dfrac{x^{2}-2xy+y^{2}}{x-y}$
Factoring the numerator,
$\displaystyle \dfrac{\left(x-y\right)^{2}}{x-y}$
Simplifying,
$\displaystyle x-y$
So
$\displaystyle \dfrac{x^{2}-2xy+y^{2}}{x-y} = {\dfrac{\left(x-y\right)^{2}}{x-y}}={x-y}$.
