See a solution process below:

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

#7u^2 + 6u + 7 + 6u^2 + 4u + 8#

Next, group like terms:

#7u^2 + 6u^2 + 6u + 4u + 7 + 8#

Now, combine like terms:

#(7 + 6)u^2 + (6 + 4)u + (7 + 8)#

#13u^2 + 10u + 15#
