By How Much is 3x3 – 2x2y + Xy2 -y3 Less than 4x3 – 3x2y – 7xy2 +2y3 - Mathematics

By how much is 3x³– 2x²y + xy² -y³ less than 4x³ – 3x²y – 7xy² +2y³

Sum

We can get the required results by substracting

3x³– 2x²y + xy² -y³ from 4x³ – 3x²y – 7xy² +2y³

= (4x³ – 3x²y – 7xy² +2y³ ) - (3x³– 2x²y + xy² -y³)

= 4x³ – 3x²y – 7xy² +2y³ - 3x³ + 2x²y - xy² + y³

= 4x³- 3x³ – 3x²y + 2x²y – 7xy² - xy² +2y³ + y³

= x³ - x²y - 8xy² + 3y³
