Subtract -4x²y - y³ from x³ + 3xy² - x²y
Solution:
Given, the expressions are -4x²y - y³ and x³ + 3xy² - x²y.
We have to subtract the expressions
On subtracting the expressions,
= x³ + 3xy² - x²y - (-4x²y - y³)
By combining the like terms,
= x³ + 3xy² - x²y + 4x²y + y³
= x³ + 3xy² + (-1 + 4)x²y + y³
= x³ + 3xy² + (3)x²y + y³
= x³ + 3xy² + 3x²y + y³
Therefore, the required expression is x³ + 3xy² + 3x²y + y³.
✦ Try This: Subtract -5x²y - 3y³ from 2x³ + 5xy² - 3x²y.
