See a solution process below:

First, rewrite the expression using just one sign for each term:

#-2 + 6c^2 - 9 - 8c - 3c - 9c#

Next, group like terms:

#6c^2 - 8c - 3c - 9c - 2 - 9#

Now, combine like terms:

#6c^2 + (-8 - 3 - 9)c + (-2 - 9) =>#

#6c^2 + (-11 - 9)c + (-11) =>#

#6c^2 + (-20)c + (-11) =>#

#6c^2 - 20c - 11#
