Answer 1

Remember that a negative sign outside parentheses changes every sign inside the parentheses.
1. Remove parentheses of the first expression. Just drop them.
2. Distribute the negative outside the second set of parentheses.
3. Combine like terms.
3x^3 - 2x^2 + 4 - 2x^2 - 14
3x^3 - 2x^2 - 2x^2 + 4 - 14
3x ^3 - 4x^2 + 10
