(X-2Y+Z)(-X+2Y+Z)因式分解 要过程

分解因式x^2(y-z)+y^2(z-x)+z^2(x-y) 分解因式:f(x,y,z)=x^2(y-z)+y^2(z-x)+z^2(x-y) x^2(-y-x)-3.2x(z+y) 分解因式 （x+y+z）³+（3x-2y-3z）³-（4x-y-2z）³分解因式分了他, x^3+x^2y-x^z-xyz分解因式 分解因式(x+y-z)(x-y+z)-(y+z-x)(z-x-y) x（x-y-z)-y(y-x+z)-z(z-x+y)分解因式 分解因式(x+y+z)(x-y+z)+(y-x+z)(y-x-z)过程. 用因式分解答1：4（x-y)²-16（x+y)² 2：（x+y-z)²-4(x-y-z)² 分解因式x^2-y^2-z^2+2yz+x+y-z (x-2y+z)^2-(x+2y-z)^2急用!不要分解因式! (x-2y+z)^2-(x+2y-z)^2急用!不要分解因式! 分解因式(x+2y-z)^2-(x-2y+z)^2 分解因式9(x+y+z)^2-(x-y-z)^2 (x+y)^2-6(x+y)z+9z^2分解因式 化简(y-x)(z-x)/(x-2y+z)(x+y-2z)+（z-y)(x-y)/(x-2z+y)(y+z-2x)+(x-z)(y-z)/(y+z-2x)(x-2y+z) 计算:(y-x)(z-x)/(x-2y+z)(x+y-2z)+(z-y)(x-y)/(x+y-2z)(y+z-2x)+(x-z)(y-z)/(y+z-2x)(x-2y+z) 计算:x^2/(x-y)(x-z)+y^2/(y-x)(y-z)+z^2/(z-x)(z-y)
