See a solution process below:

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

#7y^2 + 7y + 3 - y - 2#

Next, group like terms:

#7y^2 + 7y - y + 3 - 2#

Now, combine like terms:

#7y^2 + 7y - 1y + 3 - 2#

#7y^2 + (7 - 1)y + (3 - 2)#

#7y^2 + 6y + 1#
