發問:

factorise x^6-y^6

最佳解答:

factorise x^6-y^6 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)

其他解答:

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^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)
