Question

Subtract the product of(x²-xy+y²) and(x+y) From the product of(x²+xy+y²) and (x-y)

Answer 1

the product of
$(x + y)( {x}^{2} - xy + {y}^{2} ) = {x}^{3} + {y}^{2}$
and the product of
$(x - y)( {x}^{2} + xy + {y}^{2} ) = {x}^{3} - {y}^{3}$
ATQ
${x}^{3} - {y}^{3} - ( {x}^{3} + {y}^{3} ) \\ {x}^{3} - {x}^{3} - {y}^{3} - {y}^{3} \\ - 2{y}^{3}$
