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:

#-5y^2 - 4y + 2y^2 + 2y - 6#

Next, group like terms:

#2y^2 - 5y^2 + 2y - 4y - 6#

Now, combine like terms:

#(2 - 5)y^2 + (2 - 4)y - 6#

#-3y^2 - 2y - 6#
