Factor:
5)
3m%5E3+-+18m%5E2+%2B+15m First, factor out 3m.
3m%28m%5E2+-+6m+%2B+5%29 Now factor the parentheses.
3m%28m-1%29%28m-5%29
6)
2x%5E3+%2B+3x%5E2+-+4x+-+6
Look at the first term. The possible factors are: 2x%5E2 and x or 2x and x%5E2
Look at the last term. Possible factors are: 1*6 and 2*3
Try:
%28x%5E2-2%29%282x%2B3%29 = x%5E3+%2B+3x%5E2+-+4x+-+6
