2x-1/2[x-1/2(x-1)]=2/3(x-1)
2x-1/2[x-1/2(x-1)]=2/3(x-1)
2x-1/2[x-1/2(x-1)]=2/3(x-1)
...
原式可写为：(2x-1)*3(x-1)=2*2[x-1/2(x-1)]
即：6(2x-1)(x-1)=4[x-1/2(x-1)]
两边同时*2(x-1)即：12(2x-1)(x-1)(x-1)=8x(x-1)-4
3(2x-1)(x-1)(x-1)=2(x*x-x-1/2)=2(x-1)(x+1/2)
3(2x-1)(x-1)=2x+1
所以,6x*x-11x+2=0,即x=.自己算去

一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X

1/(1-x)+1/(1+x)+2/(1+x*x)+4/(1+x*x*x*x)+8/(1-x*x*x*x*x*x*x*x)怎么做
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,=x^2/x(x-2)+(2x-4)/x(x^2-4)-(x^2+6x)/x(x^2-4)=x^2/x(x-2)-(x+2)/x(x-2)=(x-2)(x+1)/x(x-2)=(x+1)/x
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
如果X*X--1=0,那么X*X*X+2*X*X+2008=几?
已知x*x+x-1=0 求x*x*x-2x+11=?
已知x*x+x-1=0求x*x*x-2x+2010的值
