See a solution process below:

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

#8n - 3n^4 + 10n^2 - 3n^2 - 11n^4 + 7#

Next, group like terms:

#-3n^4 - 11n^4 + 10n^2 - 3n^2 + 8n + 7#

Now, combine like terms:

#(-3 - 11)n^4 + (10 - 3)n^2 + 8n + 7#

#-14n^4 + 7n^2 + 8n + 7#
