(x²-y²)(x²+xy+y²)(x²-xy+y²)
=(x+y)(x-y)(x²+xy+y²)(x²-xy+y²)
=(x+y)(x²-xy+y²)(x-y)(x²+xy+y²)
=(x³+y³)(x³-y³)
=x^6-y^6(x的六次方-y的六次方)
希望对你有所帮助
=(x+y)(x-y)(x²+xy+y²)(x²-xy+y²)
=(x+y)(x²-xy+y²)(x-y)(x²+xy+y²)
=(x³+y³)(x³-y³)
=x^6-y^6(x的六次方-y的六次方)

(x²-y²)(x²+xy+y²)(x²-xy+y²)
=(x-y)(x+y)(x²+xy+y²)(x²-xy+y²)
=(x-y)(x²+xy+y²)*(x+y)(x²-xy+y²)
=(x^3-y^3)*(x^3+y^3)
=x^6-y^6
=(x-y)(x+y)(x²+xy+y²)(x²-xy+y²)
=(x-y)(x²+xy+y²)*(x+y)(x²-xy+y²)
=(x^3-y^3)*(x^3+y^3)
=x^6-y^6
