Question

(x-y)(x² + xy + y²) =​

Answer 1

Answer:

(x+y)(x² - xy + y²)

= x ( x² - xy + y² ) +y ( x² - xy + y²)

= x³ - x²y + xy² +yx² -xy² + y³

= x³ + y³

Answer 2

To simplify (x + -y)(x² - xy + y²)

→ (x+y)(x² - xy + y²)

⇒ x(x² - xy + y²) + y(x² - xy + y²)

x³ -x²y + xy² +x²y-xy² + y²

⇒x³+y³ - xy² + xy²

⇒x³+y³ (This is actually a identity,you can use while solving

problems)...
