(x^3-3x^2-x+3)/(x-2)化简~如题~(x^3-3x^2-x+3)/(x-2)化简~如题~(x^3-3x^2-x+3)/(x-2)化简~如题~(x^3-3x^2-x+3)=(x^3-x)
(x^3-3x^2-x+3)/(x-2)化简~如题~
(x^3-3x^2-x+3)/(x-2)化简~
如题~
(x^3-3x^2-x+3)/(x-2)化简~如题~
(x^3-3x^2-x+3)
=(x^3-x)-3(x^2-1)
=x(x^2-1)-3(x^2-1)
=(x-3)((x^2-1)
所以原式=(x-3)((x^2-1)、(x-2)
分母是x-3就更好了.!
(x^3-3x^2-x+3)/(x-2)
=[(x-3)x^2-(x-3)]/(x-2)
=(x-3)(x^2-1)/(x-2)
=(x-3)(x-1)(x+1)/(x-2)
