DSolve[Derivative[1][y][x] == (y[x]*(-1 - Log[((-1 + x)*(1 + x))/x] + x*Log[((-1 + x)*(1 + x))/x]*y[x]))/x,y[x],x]

dsolve(diff(y(x),x) = y(x)*(-1-ln((x-1)*(1+x)/x)+ln((x-1)*(1+x)/x)*x*y(x))/x,y(x))
 

\[y \left (x \right ) = \frac {1}{c_{1} x^{\ln \left (\frac {\left (x -1\right ) \left (1+x \right )}{x}\right )-\ln \left (1+x \right )+1} {\mathrm e}^{\operatorname {dilog}\left (x \right )} {\mathrm e}^{\frac {\ln \left (x \right )^{2}}{2}} {\mathrm e}^{-\operatorname {dilog}\left (1+x \right )}+x}\]
