Equating the two sides we get: (s2 +4s+8)X(s) = 1 s+1 X(s) = 1 (s+1)(s2 +4s+8) = 1 (s+1)((s+2)2 +4). The partial fraction decomposition of this rational function is X(s) = 1 5 s+1 + −1s− 3 (s+2)2 +4) = 1 5 1 s+1 − 1 5 s+2 (s+2)2 +4 − 1 10 2 (s+2)2 +4 .

Webs 2 − 4 s + 5 has zeroes at s ± = 2 ± i. The ILT f ( t) is simply the sum of the residues of 2 s + 1 s 2 − 4 s + 5 e s t at these poles. Then f ( t) = 2 s + + 1 2 s + − 4 e s + t + 2 s − + 1 2 s − − 4 e s − t Expanding this a bit: f ( t) = e 2 t [ ( 1 − i 5 2) ( cos t + i sin t) + ( 1 + i 5 2) ( cos t − i sin t)] Simplifying, I get
