x^6-y^6= (x+y)* (x^5-yx^4+y^2x^3 -y^3x^2 +y^4x -y^5)
So dividing by (x+y) the result is the second factor above

X^6 - Y^6 / X+Y
X^5 - Y ^5
Since its divide you will subtract

first factor out (x^2-y^2) in the top and the rest will follow

x^6 - y^6 / x + y
(X^3-y^3)(x^3+y^3)/(x+y)
= (x-y)(x^2+xy+y^2)(x^3+y^3)/(x+y)
= (x-y)(x^2+xy+y^2)(x+y)(x^2-xy+y^2)/(x+y)
=(x-y)(x^2+xy+y^2)(x^2-xy+y^2)
