Question

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

Answer 1

x3-x2y +y2x +x2y +-xy2+y3
X3+y3

Answer 2

Solution :

_____________________________________________________________

Given :

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 + y³

⇒ x³ + y³ - x²y + x²y - xy² + xy²

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