分解因式:(1):x(x-y)+y(y-X)多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是多少?分解因式:(1):x(x-y)+y(y-X)多项式(x+y-z)(x-y+z

分解因式:(1):x(x-y)+y(y-X) 多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是多少?
分解因式:(1):x(x-y)+y(y-X) 多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是多少?

分解因式:(1):x(x-y)+y(y-X) 多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是多少?
:(1): x(x-y)+y(y-X)=(X-Y)(x-y)=(x-y)^2
多项式(x+y-z)(x-y+z)-(y+z-X)(Z-x-y)的公因式是(x+y-z)
