分解因式(x+y-z)(x-y+z)-(y+z-x)(z-x-y)
分解因式(x+y-z)(x-y+z)-(y+z-x)(z-x-y)
分解因式(x+y-z)(x-y+z)-(y+z-x)(z-x-y)
(x+y-z)(x-y+z)-(y+z-x)(z-x-y)
=(x+y-z)(x-y+z)+(y+z-x)(x+y-z)
=(x+y-z)(x-y+z+y+z-x)
=2z(x+y-z)
(x+y-z)(x-y+z)-(y+z-x)(z-x-y)
=(x+y-z)(x-y+z)+(y+z-x)(x+y-z)
=(x+y-z)(x-y+z+x+y-z)
=2x(x+y-z)
原式=(x+y-z)(x-y+z)-(x+y-z)(x-y-z)
=(x+y-z)×2z
=2xz+2yz-2z^2
=(x+y-z)(x-y+z)+(y+z-x)(x+y-z)
=(x+y-z)(z+z)
=…
做题目前要好好看看啊…可不能马虎…呵呵…
