还有别的方法吗?
追答有,你稍等
(x-y)²+y(y-x)因式分解?
因式分解 (x-y)²+y(y-x)=(x-y)²-y(x-y)=(x-y-y)(x-y)=(x-2y)(x-y)
(x-y)²+y(y-x)因式分解?
(x-y)²=(y-x)²,提取y-x。=(y-x)(2y-x)
(x-y)²-(y-x)因式分解为?过程
(x一y)²一(y一x)=(x一y)²十(x一y)=(x一y)(x一y十1)。
因式分解下列式子:x(x-y)+y(y-x)=?要有过程哦
x(x-y)+y(y-x)=x(x-y)-y(x-y)=(x-y)(x-y)=(x-y)²明教为您解答,如若满意,请点击[满意答案];如若您有不满意之处,请指出,我一定改正!希望还您一个正确答复!祝您学业进步!
x²(x-y)+y²(y-x)因式分解
您好:x²(x-y)+y²(y-x)=x²(x-y)-y²(x-y)=(x²-y²)(x-y)=(x+y)(x-y)(x-y)=(x+y)(x-y)²如果本题有什么不明白可以追问,如果满意请点击“选为满意答案”如果有其他问题请采纳本题后另发点击向我求助,答题不易,请谅解,...
x(x-y)²-y(y-x)²因式分解,求步骤
(x-y)²(x+y)
因式分解:x²(x-y)+(y-x) 解分式方程:
x²(x-y)+(y-x)=(x-y)(x²-1)=(x-y)(x+1)(x-1)两边同时乘以x^2-2x 4+(x-2)=3x 4+x-2=3x 3x-x=4-2 2x=2 x=1 不懂可追问,有帮助请采纳,谢谢!
因式分解(x-y)²-(y-x)
(x-y)²-(y-x)=(x-y)²+(x-y)=(x-y)(x+y+1),错在没有转化-(y-x)=x+y上!
x²(x-y)+y²(y-x)
因式分解吗?如果是:原式=x²(x-y) + y²[-(x-y)]=x²(x-y) - y²(x-y)=(x-y)(x²-y²)=(x-y)(x+y)(x-y)=(x+y)(x-y)²
