See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

#2 - 2n^2 + 6n^3 + 7n^3 + 3 - 2n^4#

Next, group like terms:

#-2n^4 + 6n^3 + 7n^3 - 2n^2 + 2 + 3#

Now, combine like terms:

#-2n^4 + (6 + 7)n^3 - 2n^2 + (2 + 3)#

#-2n^4 + 13n^3 - 2n^2 + 5#
