the smallest factor of the coefficients is 4, and the smallest factor of the n is n^2.

yeah i know and the answer is supposed to be 4n^2(7n10) (n+2)..........but how do i get that after in factor out 4n^2 and factored further and have 4n^2(7n^210n+14n20)

okay backing up 4n^2(7n^2+4n20) , working on the trinomial in the parentesis you need to find two numbers when multiplied equal 20 and when added equal 4. You have a coefficient in front of n^2, so you have to take that into consideration. A good thing to do is to take the factored answer and FOIL it to see how it turns into the trinomial inside the parenthesis

(7n10)(n+2) =7n^2+14n10n20 Do you see it?
