get rid of the parenthesiss and combine like terms:
2u^3 + 2u^3
3 + 6
are the only like terms you need to combine.  now write out the whole sum including the ones that didn't have other like terms.

anonymous · Answer

do I add the "to the power" numbers as well, or does that remain a 3?

anonymous · Answer

no.... that's what makes them "like" terms. so DO NOT add the exponents.

anonymous · Answer

what's the answer you got?

anonymous · Answer

thank you. ... I got ...4u^3 + 6u^2 – 7u + 9	is that right?
