First remove the parentheses. The first set of parentheses is not needed, so just drop them. To remove the second set of parentheses, you need to distribute the negative sign as a -1 by what's inside the second set of parentheses. 5x^3 - x + 14 - 3x^2 + 9x - 4 Now combine like terms. Can you do that?
