Answer:
The solution to the given expression is -x³ + 9x + 6
Step-by-step explanation:
(9x - 4x² + 9) + (-x³ + 4x² - 3)
Since there is a positive sign in front of the second parentheses, then the terms inside will stay the same.
9x - 4x² + 9 - x³ + 4x² - 3
Group terms together that are alike. Also known as like terms.
-x³ + (-4x² + 4x²) + 9x + (9 - 3)'
Combine like terms.
-x³ + 9x + 6
