find the inverse laplace of 1/((s^2+8s+17)(1+e^(-pi*s))) here second shifting can be applied but how as e^(-pi*s) is in the denominator please help

You have to expand $\displaystyle \frac{1}{(1+e^{-\pi s})}$ as an infinite series.
what is the expansion series of 1/(1+e^-x)
Make use of the binomial expansion, $\displaystyle \frac{1}{1+x}=1-x+x^{2}-x^{3}+x^{4}- \dots.$
