当a为何值时,方程1/(x*2-1)+2a/(x+1)-1/(x-1)=0无解当a为何值时,方程1/(x*2-1)+2a/(x+1)-1/(x-1)=0无解当a为何值时,方程1/(x*2-1)+2a/

当a为何值时,方程1/(x*2-1)+2a/(x+1)-1/(x-1)=0无解
当a为何值时,方程1/(x*2-1)+2a/(x+1)-1/(x-1)=0无解

当a为何值时,方程1/(x*2-1)+2a/(x+1)-1/(x-1)=0无解
1/(x*2-1)+2a/(x+1)-1/(x-1)=0
[(2a-1)x-2a]/(x*2-1)=0
所以,当2a-1=0时,方程无解
解得:a=1/2
