~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

%28x%5E2+%2B+3x+-18%29%2F%28x%5E2+-+36%29 =         (Factor the numerator and denominator)

= %28%28x%2B6%29%2A%28x-3%29%29%2F%28%28x-6%29%2A%28x%2B6%29%29 =     (cancel common factors (x+6) ASSUMING that x =/= 6. This is a restriction)

= %28cross%28%28x%2B6%29%29%2A%28x-3%29%29%2F%28%28x-6%29%2Across%28%28x%2B6%29%29%29 = 

=%28x-3%29%2F%28x-6%29

under the restriction x=/=6.

Please be more polite: write more accurately next time.
Thanks.
