Factorize the coefficients and constant term. You can judge what to do from that.

3x%5E3%2B3%2A6%2Ax%5E2-5x-5%2A5

3%28x%5E3%2B6x%5E2%29-5%28x%2B5%29

3x%5E2%28x%2B6%29-5%28x%2B5%29----------this is not a very meaningful factorization but nothing else to be done through grouping. You made a small sign mistake.
