Answer:
b
Step-by-step explanation:
Distribute parenthesis and collect like terms, noting that the second parenthesis is distributed by - 1
(4x² - 8xy +2y²) - (9x² - 4xy - 7y²)
= 4x² - 8xy + 2y² - 9x² + 4xy + 7y² ← collect like terms
= (4x² - 9x²) + (- 8xy + 4xy) + (2y² + 7y²)
= - 5x² - 4xy + 9y² → b
