You can put this solution on YOUR website!
First +%28a%2Fb%29%2F%28c%2Fd%29+ is equivalent to +%28a%2Fb%29%2A%28d%2Fc%29+, So +%28%28x%5E2%2B8x%2B12%29%2F%28x-5%29%29%2F%28%283x%2B18%29%2F%28x%5E2-25%29%29+ is the same thing as +%28%28x%5E2%2B8x%2B12%29%2F%28x-5%29%29%2A%28%28x%5E2-25%29%2F%283x%2B18%29%29+

Now, we factorise what we can and hopefully cancel like terms out as we go:

+%28+%28x%2B2%29+%29%2A%28+%28x%2B5%29%2F%283%29+%29+
+%28+%28x%2B2%29%28x%2B5%29+%29%2F3+
