分解因式：（1):x(x-y)+y(y-X) 多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是多少?

：（1): x(x-y)+y(y-X)=(X-Y)(x-y)=(x-y)^2
多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是(x+y-z)

分解因式：（1):x(x-y)+y(y-X) 多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是数学多项式(x+y-z)(x-y+z)-(y+z-x)(z-x-y)公因式分解因式x^2(y-z)+y^2(z-x)+z^2(x-y) 初一数学分解因式题x(x-y-z)-y(y-x+z)-z(z-x+y),看清符号呀~ 分解因式:f(x,y,z)=x^2(y-z)+y^2(z-x)+z^2(x-y) (x+y-z)(x-y+z)= z/(x-y) × y/(x+y) (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=?
