    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!

    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}.
