(x+y+z)+(x-y-z)-(x-y+z)先去括号,再合并同类项急死了.
(x+y+z)+(x-y-z)-(x-y+z)先去括号,再合并同类项
急死了.
(x+y+z)+(x-y-z)-(x-y+z)先去括号,再合并同类项急死了.
(x+y+z)+(x-y-z)-(x-y+z)
=x+y+z+x-y-z-x+y-z
=x+y-z
x-y/(z-x)(z-y) 一y-z/(x-y)(x-z) ＋z-x/(y-z)(y-x)
x^-(y-z)^/(x+y)^-z^
计算（x+y-z)(x-y-z)
计算：(x-y+z)(-x+y+z)
(x+y-z)(x-y+z)=
x y y ...y z x y ...y z z x ...y ........z z z ...x 求解行列式.
x+y>z 0
用乘法公式计算(x+y)(x-y)+(-y-z)(-y+z)+(-x+z)(z+x)
计算：（X+y+z)(-x+y+z)(x-y+z)(x+y-z)
（x+y-z）（x-y+z）-（x+y+z）（x-y-z）
因式分解 ：（x+y-z)(x-y-z)+(y-x+z)(y-x-z)
因式分解测试题x(x+y-z)+y(x+y-z)+z(z-x-y)
(x+y+z)(-x+y+z)(x-y+z)(x+y-z)等于什么?
(x-y+z)²
（x+y-z）*（x+y-z)-(x-y+z)*(x-y-z)等于多少
计算(x+y+z)(-x+y+z)(x-y+z)(x+y-z)
如何化简(x+y+z)(x+y-z)(x-y+z)(-x+y+z)
