Indefinite Integration

$\frac{9}{14} \tan ^{-1}\left(\frac{x}{2}\right)+\frac{5}{14 \sqrt{3}} \log \left(\frac{x-\sqrt{3}}{x+\sqrt{3}}\right)+\mathrm{c}$, (where c is constant of integration)

$\frac{9}{7} \tan ^{-1}\left(\frac{x}{2}\right)+\frac{5}{7 \sqrt{3}} \log \left(\frac{x-\sqrt{3}}{x+\sqrt{3}}\right)+c$, (where c is constant of integration)

$\frac{9}{7} \tan ^{-1}\left(\frac{x}{2}\right)-\frac{5}{7 \sqrt{3}} \log \left(\frac{x-\sqrt{3}}{x+\sqrt{3}}\right)+\mathrm{c}$, (where c is constant of integration)
