subtract and simplify, if possible


I can't write out the actual problem

it is x squared over x minus 6 subtract 36 over 6 minus x

Is that it?

\frac{x^2}{x-6} - \frac{36}{6-x}

If so, first find the LCM (or lowest common multiple) to make them a single fraction. Expand the numerator. Then you should be able to continue, by simplifying the numerator and factorising.

However, there's a faster way of doing it. Try with the way I told you, and we'll see for the other, faster way.
