分式加减 (x-y)(z-y)/x+y - (y-x)(y-z)/x+z 不要跳步骤,
(x-y)(z-y)/x+y - (y-x)(y-z)/x+z
=(x-y)(z-y)(x+z)/(x+y)(x+z) - (y-x)(y-z)(x+y)/(x+z)(x+y)
=[(x-y)(z-y)(x+z) - (y-x)(y-z)(x+y)]/(x+z)(x+y)
={(x-y)(z-y)(x+z) -[- (y-x)][-(y-z)](x+y)}/(x+z)(x+y)
=[(x-y)(z-y)(x+z) -(x-y)(z-y)(x+y)]/(x+z)(x+y)
=(x-y)(z-y)[(x+z) -(x+y)]/(x+z)(x+y)
=(x-y)(z-y)(x+z -x-y)/(x+z)(x+y)
=(x-y)(z-y)(z -y)/(x+z)(x+y)
=(x-y)(z-y)²/(x+z)(x+y)
=(x-y)(z-y)(x+z)/(x+y)(x+z) - (y-x)(y-z)(x+y)/(x+z)(x+y)
=[(x-y)(z-y)(x+z) - (y-x)(y-z)(x+y)]/(x+z)(x+y)
={(x-y)(z-y)(x+z) -[- (y-x)][-(y-z)](x+y)}/(x+z)(x+y)
=[(x-y)(z-y)(x+z) -(x-y)(z-y)(x+y)]/(x+z)(x+y)
=(x-y)(z-y)[(x+z) -(x+y)]/(x+z)(x+y)
=(x-y)(z-y)(x+z -x-y)/(x+z)(x+y)
=(x-y)(z-y)(z -y)/(x+z)(x+y)
=(x-y)(z-y)²/(x+z)(x+y)
分式约分:(y+z-x)/{x^2-(y+z)^2}
已知x+y-z/z=x-y+z/y=-x+y+z/x,且xyz不等于0,求分式[(x+y)(x+z)(y+z)]/xyz
(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
z/(x-y) × y/(x+y)
①(x+y+z）（-x+y+z）(x-y+z)(x+y-z)
数学 多项式(x+y-z)(x-y+z)-(y+z-x)(z-x-y)公因式
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
