Answer:

8x² - 2y²

Step-by-step explanation:

Sum of 2x² - 3y², 9x² + 6y², -3x² -5y²

=> (2x² - 3y²) + (9x² + 6y²) + (-3x² - 5y²)

=> 2x² - 3y² + 9x² + 6y² - 3x² - 5y²             (Minus and minus combine to become plus)

=> 2x² + 9x² - 3x² - 3y² + 6y² - 5y²             (Grouping like terms)

=> 8x² - 2y²
