Question

(x-y)x^6+(y-x)y^6因式分解

要用到立方差或立方和公式（应该是要的）

Answer 1

(x-y)x^6+(y-x)y^6

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

Answer 2

(x-y)x^6+(y-x)y^6

=(x-y)(x^6-y^6)
=(x-y)(x³+y³)(x³-y³)

Answer 3

(x-y)x^6+(y-x)y^6
=(x-y)x^6-(x-y)y^6
=(x-y)(x^6-y^6)
=(x-y)(x³+y³)(x³-y³)
=(x-y)(x+y)(x²-xy+y²)(x-y)(x²+xy+y²)
=(x-y)²(x+y)(x²-xy+y²)(x²+xy+y²)

Answer 4

解: (x-y)x^6+(y-x)y^6
=(x-y)x^6-(x-y)y^6
=(x-y)(x^6-y^6)
=(x-y)(x³+y³)(x³-y³)
=(x-y)(x+y)(x²-xy+y²)(x-y)(x²+xy+y²)
=(x-y)²(x+y)(x²-xy+y²)(x²+xy+y²)

Answer 5

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