(x-y-z)乘以(z-x+y)等于?
(x-y-z)乘以(z-x+y)等于?
(x-y-z)乘以(z-x+y)等于?
(x-y-z)(z-x+y)=(x-y-z)[-(x-y-z)]=-(x-y-z)²
(x+y-z)乘以(x-y-z)等于?
(x-y-z)乘以(z-x+y)等于?
(x+y-z)*(x+y-z)-(x-y+z)*(x-y-z)等于多少
已知x乘以y等于z(z不等于0)那么:当z一定时,x和y成:
(x-y+z)(x+y+z)等于多少.
(x-y+z)(x+y+z)等于多少?
(x+y-z)(x-y+z)-(x+y+z)(x-y-z)
(x+y+z)(x-y+z)+(y-x+z)(y-x-z)求过程
X乘以Y等于Z,已知X与Z求Y?
(x+y+z)(-x+y+z)(x-y+z)(x+y-z)等于什么?
z分之x+y等于y分之x+z等于x分之y+z(x+y+z不等于零)求x+y+z分之x+y-z的值
z分之x+y等于y分之x+z等于x分之y+z(x+y+z不等于零)求x+y+z分之x+y-z的值
若x,y,z成等差数列,则(Z-X)^2-4(X-Y)(Y-Z)等于
x分之y+z=y分之z+x=z分之x+y(x+y+z不等于0),求x+y+z分之x+y-z
分式加减法:已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z
已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z的步骤
已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z的步骤
X平方乘以Y-Z的差+Y平方乘以Z-X的差+Z平方乘以X-Y的差等于多少
