The integral given is $\int_{\mathbb{R}}(a+bt^2)^{-m} dt$ where $a,b >0, m\in\mathbb{N}$. According to the Residue Theorem, if $\lim_{z\rightarrow\infty,\Im(z)>0}zf(z)=0$ then $$\int_{-\infty}^\infty f(t) dt = 2\pi i \sum_{\Im(z)>0} \operatorname{Res}_z(f)$$. Now first I see that $z(a+bz^2)^{-m} ...
