Question

product of (x 2 + xy + 2y2 ) (x – y)

Answer 1

Answer:

x^3 - 2 y^3 -xy^2

Step-by-step explanation:

x^3 +x^2y +2xy^2 - x^2 y -xy^2 -2y^3

x^3 - 2y^3 + 2xy^2 - xy^2

Ans. x^3 - 2 y^3 - xy ^2.

Sorry for some inconvenience it will be a little bit hard to read.

Answer 2

Answer:

$x^{3} +xy^{2} -2y^{3}$

Step-by-step explanation:

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

$=(x^{2} *x)+(x^{2}* -y)+(xy*x)+(xy*-y)+(2y^{2} *x)+(2y^{2} *y)=x^{3} -x^{2} y+x^{2} y-xy^{2} +2xy^{2} -2y^{3}$

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