Dividing equations? Long time--have forgotten how
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!(Sweating)

Original expression:
$\dfrac{x^{2}-2xy+y^{2}}{x-y}$

Factoring the numerator,
$\dfrac{\left(x-y\right)^{2}}{x-y}$

Simplifying,
$x-y$

So
$\dfrac{x^{2}-2xy+y^{2}}{x-y} = {\dfrac{\left(x-y\right)^{2}}{x-y}}={x-y}$.
