$ \ h(t) = 5e^{-t} $


$ \ H(jw) = 5\int_0^{\infty} e^{-\tau}e^{-jw{\tau}}\,d{\tau} $

$ \ H(jw) = 5[-\frac{1}{1 + jw}e^{-\tau}e^{-jwr} ]^{\infty}_0 $

$ \ H(jw) = \frac{5}{1+ jw} $


So,

$ \ b_{0} = 0 $


$ \ b_{1} = (\frac{1 + 2j}{2}) (\frac{5}{1+jw}) $

$ \ b_{-1}= (\frac{1 + 2j}{2}) (\frac{5}{1 - j}) $

$ \ b_{2} = (\frac{5}{2j}) (\frac{5}{1+5j}) $

$ \ b_{-2}= (\frac{5}{2j}) (\frac{5}{1-5j}) $


So,

$ \ y(t) = (\frac{1 + 2j}{2}) (\frac{5}{1+jw})e^{jt} + (\frac{1 + 2j}{2})e^{-jt} (\frac{5}{1 - j}) + (\frac{5}{2j}) (\frac{5}{1+5j})e^{j4t} + (\frac{5}{2j}) (\frac{5}{1-5j})e^{-j4t} $
