hi having a problem trying to solve this rational expression
Equations are solved; expressions are simplified. Do the instructions say to "solve" or to "simplify", or something else? I will guess "simplify".

2x-9 x-9
____ - _______
x(x-3) x(x-3)
I will guess that this means the following:
. . . . .(2x - 9)/(x(x - 3)) - (x - 9)/(x(x - 3))
...or, in LaTeX:
. . . . .\(\displaystyle \large{\frac{2x\,-\,9}{x(x\,-\,3)}\, -\,\frac{x\,-\,9}{x(x\,-\,3)}}\)
If so, then just combine the two numerators, simplify, and then cancel the common factor.

It is simple to check their equality: Either evaluate them at a few different x-values and verify that they return the same result. (For instance, what is the result if you evaluate each at x = 2?) Or else graph each in your calculator, and verify that they display the same graph.
If you are unsatisfied with the results, please reply showing how you arrived at your answer. Thank you.
