Grouping for factoring: Group terms to prepare for factoring by grouping. Group the first two terms and the last two terms separately. 6m3−6m2 + m−1
Factor out common factors: Factor out the greatest common factor from each group.From the first group, factor out 6m2. From the second group, factor out 1.6m2(m−1)+1(m−1)
Factor out (m−1): Notice that (m−1) is a common factor in both groups.Factor out (m−1) from the entire expression.(m−1)(6m2+1)
Check for further factoring: Check to see if the factored terms can be factored further. 6m2+1 is a sum of squares and cannot be factored over the real numbers. The factored form is (m−1)(6m2+1).
