This is a question from pre algebra, factoring by grouping.
2m2(m+4) + 5(m+4) - original expression
Hi Summer... I'm not sure what you need as an end result, but here are two possibilities:
2m3 + 8m2 + 5m + 20 - do the multiplications
(m+4) (2m2 + 5) - pull out the common term, (m+4). (2M2 + 5) won't factor further.
