Hi,

2x%5E2%2F%282x%5E3-18x%29+%2B+15%2F%285x-15%29 

2x%5E2%2F%282x%29%28x%5E2-9%29+%2B+15%2F5%28x-3%29   

x%2F%28x%5E2-9%29+%2B+3%28x%2B3%29%2F%28x-3%29%28x%2B3%29+    |Note (x^2-9) = (x-3)(x+3)  

   x%2F%28x%5E2-9%29+%2B+3%28x%2B3%29%2F%28x%5E2-9%29+ 

   %28x+%2B+3x%2B9%29%2F%28x%5E2-9%29+ 

  %284x%2B9%29%2F%28x%5E2-9%29
