Homework Help: Show an equality is true

  1. Dec 22, 2005 #1
    How could I show that this is true:
    [tex]\frac{m^2g^2-m^2}{ma+za}-\frac{zamg}{am+az+gm+gz}=-\frac{zma^2-z^2a^2}{ma-mg}[/tex]

    Where does that expression come from? It doesn't look true to me. (Plug in a few values and see for yourself.)

    yeah, it's not true...well, that makes it easy to show it's not true.
