Question

(x - y)(x2 + 2xy - y)
multiply pls

Answer 1

x³ + x²y - 2xy² - xy + y²

Explanation:

Given

(x - y)(x² + 2xy - y)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + 2xy - y) - y(x² + 2xy - y) ← distribute both parenthesis

= x³ + 2x²y - xy - x²y - 2xy² + y² ← collect like terms

= x³ + x²y - 2xy² - xy + y²

Answer 2

as below

Explanation:

(x-y)(
`x^(2)`+2xy-y)

`x^(3)`+2
`x^(2)`y-xy-
`x^(2)`y-2x
`y^(2)`+
`y^(2)`

`x^(3)`+
`x^(2)`y-xy-2x
`y^(2)`+
`y^(2)`
