Before canceling anything, we can get:
%28a%28a%2B1%29%5E2%2A15%2Ab%5E2%2A%28b%2B1%29%29%2F%283b%2A%28a%2B1%29%29
Since, 15%2F3+=+5 , b%5E2%2Fb+=+b}, %28a%2B1%29%5E2%2F%28a%2B1%29=%28a%2B1%29
That leaves us with, a%2A%28a%2B1%29%2A5%2Ab%2A%28b%2B1%29=5%2A%28a%5E2%2Ba%29%2A%28b%5E2%2Bb%29
You could go further, if necessary.
