x3-3x2+x+1=0怎么变成(x-1)(x2-2x-1)=0请尽快回答
(x³-x²)-(x²-x)-(x²-1)=0
x²(x-1)-x(x-1)-(x+1)(x-1)=0
(x-1)(x²-x-x-1)=0
(x-1)(x²-2x-1)=0

x3-3x2+x+1=0
x3-x2-2x2+2x-x+1=0
x2(x-1)-2x(x-1)-(x-1)=0
(x-1)(x2-2x-1)=0

x3－2x2－x2－x＋2x＋1＝x (x2－2x－1)－(x2－2x－1)＝(x－1)(x2－2x－1)

x3-3x2+x+1=0怎么变成(x-1)(x2-2x-1)=0请尽快回答 x2-x-1=0,-x3+2x2+2008= X2+x-1=0,那么x3 + X2+2008= 已知X3+X2+X+1=0,求1+X+X2+X3+X4的值 1+X+X2+X3=0,X+X2+X3+~+X2000=? 因式分解 X3-3X2+X+1=0 已知x2+5x-4=0,求x3+6x2+x+2的值已知x2+x-1=0,求x3+2x2+3的值若 x2-3x+1=0,求（2x2×x3-5x2×x2+2 x3-8x2 ）÷（x2+1 ）的值已知x2+x-3=0,那么(3-x2-x3)/(x-1)=? 已知x2-3x-1=0求x3-3x2-11x+8的值已知X2-X-1=0求,X5-X4-3X3+3X2+X的值若x2+3x-1=0,则x3+5x2+5x+18=? X2+X+1=0 X4+2X3+4X2+3X+2=? x2+3x-1=0,求x3+5x2+5x+2010的值已知x2-3x+1=0,求x4-6x3+4x2+15x+2 x3-x2-3x+2=0怎么解 y=In(x3+x)+x2+1怎么求导 x2+3x+1=0,求x3+1/x3与x7+1/x7的值.
