comment What is suitable contour shape for $\int_0^\infty\dfrac{b^2+2ab+k}{b(b^2+ab+l)}e^{bx}~db$
It has simple poles(singularity points) at $b=0, -a/2 \pm \sqrt{a^2-4l}/2 $. To solve such integrals, we take help of contour integration, and residue theorem. I am not able to find proper contour to solve this integration.
