Answer:
11x²y³ - 4xy²
Step-by-step explanation:
remove the parenthesis and collect like terms
4x²y³ + 2xy² - 2y + 7x²y³ - 6xy² + 2y
= (4x²y³ + 7x²y³) + (2xy² - 6xy²) + (- 2y + 2y)
= 11x²y³ - 4xy² + 0
= 11x²y³ - 4xy²
The difference of the two polynomials is: 11x²3y³ - 4xy² .
The difference between two polynomials is the result you get by subtracting one from the other.
Thus:
(4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)
Open bracket
4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y
11x²3y³ - 4xy²
Therefore, the difference of the two polynomials is: 11x²3y³ - 4xy² .
