Question

(x + y)(x^2 - xy + y^2) helppp:(

Answer 1

Multiply each item as follows (multiply each item in the left-hand side with each item in the right-hand):

(x)(x^2)=x^3
(x)(-xy)=-x^2y
(x)(y^2)=xy^2
(y)(x^2)=yx^2=x^2y
(y)(-xy)=-xy^2
(y)(y^2)=y^3

Now combining this you get:

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

The answer is: x^3+y^3
