Answer:
Step-by-step explanation:
Given that,
( x³ + x²y + xy² - y³ ) + ( 3x³ + 2x²y - 2xy² - y³ )
= x³ +x²y + xy² - y³ + 3x³ + 2x²y - 2xy² - y³
= ( x³ + 3x³ ) + ( x²y + 2x²y ) + ( xy² - 2xy² ) + ( - y³ - y³ ) (∵Like terms adding )
= 4x³ + 3x²y - xy² + ( - 2y³ )
= 4x³ + 3x²y - xy² - 2y³ is the answer. ( ∵ + × - = - )
