Hi Jaimi,

   This looks like a classic case of "combining like terms."  Since there is no multiplication or division within the parentheses, you can just remove them.  Then, add 3n3 + 4n3 and subtract 2n2 - n2.  So, what do you get?   7n+ n2.  (The convention is to write the variables with the higher/est exponents first, in an algebraic expression.)
