2x(x - y2) – 3y(xy + 2x) – xy(x + y)
=2x^2 - 2xy^2 -3xy^2 - 6xy - x^2y - xy^2
here is ur answer
if this answer helps u then do follow me...
Answer:
Step-by-step explanation:
Given 2x(x - y2) – 3y(xy + 2x) – xy(x + y)
So we need to first multiply...
2x square + 4xy - 3xy square + 6xy - x square y + xy square
Now solve it with similar terms like
4xy + 6xy = 10xy
- 3xy square + xy square = -2xy square
=> 10xy - 2xy square - x square y
