Answer 2

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow (x-y)(x^2+xy+y^2)$

WE KNOW,

$\large{\boxed{\bf{ \star\:\: a^3-b^3= (a-b)(a^2+ab+b^2)}}}$

$\large\underline\bold{SOLUTION,}$

$\sf\implies x^3+x^2y+xy^2-x^y-xy^2-y^3$

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

$\sf\implies x^3-y^3,$

$\sf\implies or \: (x-y)^3+3ab(a-b)$

$\large{\boxed{\bf{ \star\:\: = x^3-y^3\:\: \star}}}$
