I need double checking. http://i45.tinypic.com/jqjoep.jpg I got the answer "1"... need someone to make sure if that's right.
Interesting, gotta figure out what I did wrong.
\[\frac{x^2-1}{(x-2)(x+1)}-\frac{(x-1)(x+1)}{(x-2)(x+1)}\]\[=\frac{x^2-1}{(x-2)(x+1)}-\frac{x^2-1}{(x-2)(x+1)}=\frac{x^2-1-(x^2-1)}{(x-2)(x+1)}\]\[=\frac{0}{(x-2)(x+1)}=0\]
Thanks, appreciate it.
