See the entire solution process below:

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

#2n + 2n^2 - 5 + 2n^4 - 2 - 8n#

Next, group like terms:

#2n^4 + 2n^2 + 2n - 8n - 5 - 2#

Now, combine like terms:

#2n^4 + 2n^2 + (2 - 8)n + (-5 - 2)#

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