Answer 2

Answer:

-270x²y - 250y³

Step-by-step explanation:

please mark me as brainiest.

$Given Equation is (3x - 5y)³ - (3x + 5y)³∴ a³ - b³ = (a - b)(a² + b² + ab)= (3x - 5y - 3x - 5y)[(3x + 5y)² + (3x - 5y)² + (3x + 5y)(3x - 5y)]= (-10y)[9x² + 25y² + 30xy + 9x² + 25y² - 30xy + 9x² - 25y²]= (-10y)[27x² + 25y²]= -270x²y - 250y³$
