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:

#2c^2 - 8 - 3c^2 + 4c - 1#

Next, group like terms:

#2c^2 - 3c^2 + 4c - 8 - 1#

Now, combine like terms:

#(2 - 3)c^2 + 4c - (8 + 1)#

#-1c^2 + 4c - 9#

#-c^2 + 4c - 9#
