✔ 最佳答案
factorise x^6-y^6x^6 - y^6
=(x^3)^2 - (y^3)^2
=(x^3 + y^3)(x^3 - y^3)
=(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)

x^6-y^6
=(x^3)^2-(y^3)^2
=(x^3+y^3)(x^3-y^3)
=(x+y)(x^2+xy-x^2)(x-y)(x^2+xy+x^2)
可以完的了= =
=(x^3)^2-(y^3)^2
=(x^3+y^3)(x^3-y^3)
=(x+y)(x^2+xy-x^2)(x-y)(x^2+xy+x^2)
可以完的了= =

x^6 - y^6
=(x^3)^2 - (y^3)^2
=(x^3 + y^3)(x^3 - y^3)
=(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)
=(x^3)^2 - (y^3)^2
=(x^3 + y^3)(x^3 - y^3)
=(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)

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