用换元法解方程2xx−1+x−1x=4
用换元法解方程2xx−1+x−1x=4
如果方程2xx+1−x+1x=mx
解分式方程1−xx−2+2=12−x,可知方程( )
解方程:xx−2+ x−9x−7= x+1x−1+ x−8x−6
解方程1/(xx+x)+1/(xx+3x+2)+1/(xx+5x+6)+1/(xx+7x+12)+1/(xx+9x+20
解分式方程xx+1−x+1x=kx
用换元法解分式方程2xx−1−5x−5x+3=0时,如果设xx−1=y,那么原方程可化为( )
用换元法解方程:(xx−1
当a取何值时,方程x−1x−2−2−xx+1=2x+ax
若关于x的方程2kx−1−xx
