\hspace{-0.6 cm}I = \int\frac{x^2-1}{x^3\sqrt{2x^4-2x^2+1}}dx = \int\frac{x^2-1}{x^3\cdot x^2\sqrt{2-2x^{-2}+x^{-4}}}dx$\\\\\\$=\int\frac{x^{-3}-x^{-5}}{\sqrt{2-2x^{-2}+x^{-4}}}dx\;,$ Put $2-2x^{-2}+x^{-4} = t^2\;,$ \\\\\\$\Rightarrow 4(x^{-3}-x^{-5})dx=2tdt\;,$ So $I = \frac{1}{2}\int\frac{t}{t}dt=\frac{1}{2}t+\mathcal{C}$
