Answer:
x³ + x²y - 2xy² - xy + y²
Step-by-step 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:
as below
Step-by-step explanation:
(x-y)([tex]x^{2}[/tex]+2xy-y)
[tex]x^{3}[/tex]+2[tex]x^{2}[/tex]y-xy-[tex]x^{2}[/tex]y-2x[tex]y^{2}[/tex]+[tex]y^{2}[/tex]
[tex]x^{3}[/tex]+[tex]x^{2}[/tex]y-xy-2x[tex]y^{2}[/tex]+[tex]y^{2}[/tex]
