See a solution process below:

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

$8c^3 - 3c^2 + c - 2 - 3c^3 - 9$

Next, group like terms:

$8c^3 - 3c^3 - 3c^2 + c - 2 - 9$

Now, combine like terms:

$(8 - 3)c^3 - 3c^2 + c + (-2 - 9)$

$5c^3 - 3c^2 + c + (-11)$

$5c^3 - 3c^2 + c - 11$

How do you find the sum or difference of (8c^3-3c^2+c-2)-(3c^3+9)(8c^3-3c^2+c-2)-(3c^3+9)?
