Question 64536
Factor:
5)
{{{3m^3 - 18m^2 + 15m}}} First, factor out 3m.
{{{3m(m^2 - 6m + 5)}}} Now factor the parentheses.
{{{3m(m-1)(m-5)}}}

6)
{{{2x^3 + 3x^2 - 4x - 6}}}
Look at the first term. The possible factors are: {{{2x^2}}} and {{{x}}} or {{{2x}}} and {{{x^2}}}
Look at the last term.  Possible factors are: 1*6 and 2*3
Try:
{{{(x^2-2)(2x+3)}}} = {{{x^3 + 3x^2 - 4x - 6}}}
