2是平方
=(x-y)(x^2+y^2)
=(x-y)(x²+xy+y²)-xy(x-y)
=(x-y)(x²+xy+y²-xy)
=(x-y)(x²+y²)
=x²(x-y)+y²(x-y)
=(x-y)(x²+y²)本回答被提问者采纳
【初中数学】分解因式x3-x2y+xy2-y3 帮帮忙拜托了急啊
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)
【初中数学】分解因式x3-x2y+xy2-y3?
=x²(x-y)+y²(x-y)=(x-y)(x²+y²),5,【初中数学】分解因式x3-x2y+xy2-y3 是X的立方减X平方乘y加X乘y的平方减y的立方 求老师童鞋们帮帮忙~
X3-X2y-xy2+y3 因式分解
=xy(x2-xy-xy-y2)=xy(x2-2xy-y2)=xy(x-y)2 绝对 对！ 先提公因式 之后利用完全平方公式
分解因式x3-xy2+x2y-y3
x3-xy2+x2y-y3 原式=(x^3+x^2y)-(xy^2+y^3)=x^2(x+y)-y^2(x+y)=(x+y)(x^2-y^2)=(x+y)(x+y)(x-y)=(x+y)^2(x-y)
因式分解:x3+x2y-xy2-y3(数字都是立方和平方哦)
原式 = xy(x2-xy-xy-y2)=xy(x-y)2 同学你好，如果问题已解决，记得右上角采纳哦~~~您的采纳是对我的肯定~谢谢哦
请帮解因式分解题:x3一3x2y十3Xy2一y3请求因式分解
(x-y)3=(x-y)(x2-2xy+y2)=x3一3x2y十3Xy2一y3
x3次方-xy平方+x平方y-y3次方 分解因式
x3次方-xy平方+x平方y-y3次方 =x(x²-y ²)+y(x²-y²)=(x+y)(x²-y²)=(x+y)(x+y)(x-y)=(x+y)²(x-y)很高兴为您解答，祝你学习进步！【the1900】团队为您答题。有不明白的可以追问！如果您认可我的回答。请点击下面的【选为满意回答...
将x3-x2y-xy2+y3分组分解?
选D 其它三项都可将其分解，只有D不可以，所以D的分组不恰当。
因式分解,x3+x2y-xy2-y3?
x3+x2y-xy2-y3 =x2(x+y)-y2(x+y)=(x2-y2)(x+y)=(x-y)(x+y)2
