• how to factor by grouping this 3m^3-m^2+9m-3 ??

Answer #1 | 08/02 2014 11:05
3m^3-m^2+9m-3= m^2(3m-1) + 3(3m-1) = (m^2+3)(3m-1)

Factor out m^2 from the first two sets of numbers and 3 from the last two... (m^2(3m−1)+3(3m−1)) Factor the polynomial by grouping the first two terms together and finding the GCF. Next, group the second two terms together and find the GCF. Since both groups contain the factor (3m−1), they can be combined. (m^2 +3)(3m−1)
