Question

the value of (X+y) (x² - xy +y²) is
​

Answer 1

x³-x²y+xy²+x²y-xy²+y³

=x³+y³

pls mark as brainelist

Answer 2

$\red{ The \: value \: of \: (x+y)(x^{2}-xy+y^{2})}$

$= x(x^{2}-xy+y^{2}) + y(x^{2}-xy+y^{2})$

$= x^{3} -\cancel{ x^{2}y} +\cancel { xy^{2}} +\cancel {x^{2}y} - \cancel {xy^{2}}+y^{3}$

$= x^{3} + y^{3}$

Therefore.,

$\red{ The \: value \: of \: (x+y)(x^{2}-xy+y^{2})}$

$\green { = x^{3} + y^{3}}$
