【初中数学】分解因式x3-x2y+xy2-y3 帮帮忙拜托了急啊

是X的立方减X平方乘y加X乘y的平方减y的立方 步骤详细点~求老师童鞋们帮帮忙~~~~~

Answer 1

答案是什么啊？（x-y)(x2+y2)? x3-y3-xy(x-y)=(x-y)(x2+xy+y2)-xy(x-y)=(x-y)(x2+y2)

Answer 2

(x-y)(x2+y2)

2是平方

Answer 3

X^2(x-y)+y^2(x-y)
=(x-y)(x^2+y^2)

Answer 4

x³-y³-x²y+xy²
=(x-y)(x²+xy+y²)-xy(x-y)
=(x-y)(x²+xy+y²-xy)
=(x-y)(x²+y²)

Answer 5

x³-x²y+xy²-y³
=x²(x-y)+y²(x-y)
=(x-y)(x²+y²)
