Evaluvating \int_{-\infty}^{\infty}{ \frac{x^2}{(x^2+1)^2(x^2+2x+2)} dx} by contour integration, state the poles in side C -contour real axis from -R to +R and Semicircle S above the real axis

Question

Evaluvating    \int_{-\infty}^{\infty}{ \frac{x^2}{(x^2+1)^2(x^2+2x+2)} dx}   by contour integration, state the poles in side C -contour real axis from -R to +R and Semicircle S above the real axis

Answer

z= i ~ simple ~pole~ z=1 + ~2i ~and ~poles ~of ~order ~1

Answer

z= -i ~pole ~of ~oder~ 2 ~ and ~z=-1 + ~i ~and ~poles ~of ~order ~1

Answer

z= i~ pole ~of ~order~ 2 ~ and ~z=-1 + ~2i ~and ~poles ~of ~order ~1
