Question

( x2-xy+y2)(x+y)-(x2+xy+y2)(x-y)​

Answer 1

Answer:

2y^3

Step-by-step explanation:

x[x^2 - xy + y^2] + y[x^2 - yx + y^2 ] - x[x^2 +xy +y^2] - y[x^2+xy+y^2]

x^3 - x^2y +xy^2 + yx^2 - y^2x + y^3 -[ x^3 + x^2y + xy^2 - x^2y -  xy^2 - y^3]

when we open braket sighn will b changed + will be - and - will be +

x^3 + y^3 - x^3 + y^3

2y^3
