因式分解 X^4(X-y)-y^4(X-y)
因式分解 X^4(X-y)-y^4(X-y)
因式分解 X^4(X-y)-y^4(X-y)
X^4(X-y)-y^4(X-y)
=(x-y)(x^4-y^4)
=(x-y)(x^2+y^2)(x^2-y^2)
=(x-y)(x^2+y^2)(x+y)(x-y)
=(x-y)^2(x^2+y^2)(x+y)
X^4(X-y)-y^4(X-y)
=(x-y)(x-y)(x+y)(x²+y²)

X^4(X-y)-y^4(X-y)
=(X-y)(X^4-y^4)
=(X-y)(X^2+y^2)(X^2-y^2)
=(X-y)(X^2+y^2)(x+y)(x-y)
=(X^2+y^2)(x+y)(x-y)^2
X^4(X-y)-y^4(X-y)
=(X-y)(X^4-y^4)
=(X-y)(X^2-y^2)(X^2+y^2)
=(X-y)(X-y)(X+y)(X^2+y^2)
=(X-y)^2 (X+y)(X^2+y^2)
(x-y)(x∧4-y∧4)
=(x-y)(x∧2+y∧2)(x∧2-y∧2)
=(x+y)(x-y)∧2(x∧2+y∧2)
=(x-y)(x^4-y^4)
=(x-y)(x^2-y^2)(x^2+y^2)
=(x-y)^2(x+y)(x^2+y^2),希能帮到你。
