Question

2x³ - 3x²y + 3xy² - 2y³ from x³ - xy² + 8x²y - 5y³​

Answer 1

Answer:

hope it helps you!!

Step-by-step explanation:

(x³ - xy² + 8x²y - 5y³) - (2x³ - 3x²y + 3xy² - 2y³)

= x³ - xy² + 8x²y - 5y³ - 2x³ + 3x²y - 3xy² + 2y³

= x³ - 2x³ - xy² - 3xy² + 8x²y + 3x²y - 5y³ + 2y³

= - x³ - 4xy² + 11x²y - 3y³
