(x+y-z)(x-y+z)-(y+z-x)(z-x-y)公因式 过程(x+y-z)(x-y+z)-(y+z-x)(z-x-y)=(x+y-z)(x-y+z)+(y+z-x)
为什么变成加号只有后面的变号

(x+y-z)(x-y+z)-(y+z-x)(z-x-y)公因式
过程(x+y-z)(x-y+z)-(y+z-x)(z-x-y)=(x+y-z){(x-y+z)+(y+z-x)}
(x+y-z)(x-y+z)-(y+z-x)(z-x-y)=(x+y-z)(x-y+z)+(-1)(y+z-x)(z-x-y)
=(x+y-z)(x-y+z)+(y+z-x)(-1)(z-x-y)
=(x+y-z)(x-y+z)+(y+z-x)(x+y-z)
=(x+y-z){(x-y+z)+(y+z-x)}
过程(x+y-z)(x-y+z)-(y+z-x)(z-x-y)=(x+y-z){(x-y+z)+(y+z-x)}
(x+y-z)(x-y+z)-(y+z-x)(z-x-y)=(x+y-z)(x-y+z)+(-1)(y+z-x)(z-x-y)
=(x+y-z)(x-y+z)+(y+z-x)(-1)(z-x-y)
=(x+y-z)(x-y+z)+(y+z-x)(x+y-z)
=(x+y-z){(x-y+z)+(y+z-x)}
数学 多项式(x+y-z)(x-y+z)-(y+z-x)(z-x-y)公因式
(x+y-z)(x-y+z)=
(y-x)/(x+z-2y)(x+y-2z)+(z-y)(x-y)/(x+y-2z)(y+z-2x)+(x-z)(y-z
①(x+y+z）（-x+y+z）(x-y+z)(x+y-z)
方向 X Y Z
(x+y+z)^5-(x+y-z)^5-(x+z-y)^5-(z+y-x)^5,
X+Y+Z=?
如何化简(x+y+z)(x+y-z)(x-y+z)(-x+y+z)
（x+y+z)(-x+y+z)(x-y+z)(x+y-z)怎么算
x,y,z正整数 x>y>z证明 x^2x +y^2y+z^2z>x^(y+z)*y^(x+z)*z^(x+y)
化简(y-x)(z-x)/(x-2y+z)(x+y-2z)+（z-y)(x-y)/(x-2z+y)(y+z-2x)+(x
