Question

(x + y)^3 - (x - y)^3 ?​

Answer 1

❤️Hola✌️

Answer:

2x • (x2 + 3y2)

Step-by-step explanation:

2x3 + 6xy2

= 2x • (x2 + 3y2)

Final result

2x • (x2 + 3y2)

Answer 2

Answer:

3x^2 y^2 +y^4

Step-by-step explanation:

(x+y)^3-(x-y)^3= [(x+y)-(x-y)] [(x+y)^2+(x+y)(x-y)+(x-y)^2)

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

                      =(y^2)(3x^2+y^2)

                      =3x^2+y^2
