Answer:
-x³ + x²y + xy² + y²
Step-by-step explanation:
2x³ - 3x²y + 2xy² + 3y² from x³ - 2x²y + 3xy² +
4y²
= x³ - 2x²y + 3xy² + 4y² - (2x³ - 3x²y + 2xy² + 3y²)
= x³ - 2x²y + 3xy² + 4y² - 2x³ + 3x²y - 2xy² - 3y²
= x³ - 2x³ - 2x²y + 3x²y + 3xy² - 2xy² + 4y² - 3y²
= -x³ + x²y + xy² + y²

Step-by-step explanation:
2x³ - 3x²y + 2xy² + 3y² from x³ - 2x²y + 3xy² +
4y²
= x³ - 2x²y + 3xy² + 4y² - (2x³ - 3x²y + 2xy² + 3y²)
= x³ - 2x²y + 3xy² + 4y² - 2x³ + 3x²y - 2xy² - 3y²
= x³ - 2x³ - 2x²y + 3x²y + 3xy² - 2xy² + 4y² - 3y²
= -x³ + x²y + xy² + y²
