Step-by-step explanation:
<u>Step 1: Define</u>
(3x² - 3x + 6) - (5x² + 2x + 9)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute negative: 3x² - 3x + 6 - 5x² - 2x - 9
- [Subtraction] Combine like terms (x²): -2x² - 3x + 6 - 2x - 9
- [Subtraction] Combine like terms (x): -2x² - 5x + 6 - 9
- [Subtraction] Combine like terms (Z): -2x² - 5x - 3
