Answer 1

Step-by-step explanation:

(x+y)(x

(x+y)(x 2

(x+y)(x 2 −xy+y

(x+y)(x 2 −xy+y 2

(x+y)(x 2 −xy+y 2 )

(x+y)(x 2 −xy+y 2 )=x(x

(x+y)(x 2 −xy+y 2 )=x(x 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y −

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y 3

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y 3

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y 3 =x

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y 3 =x 3

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y 3 =x 3 +y

(x+y)(x 2 −xy+y 2 )=x(x 2 −xy+y 2 )+y(x 2 −xy+y 2 )=x 3 −x 2 y+xy 2 +x 2 y − xy 2 +y 3 =x 3 +y 3
