WebbYou may want to try this (slighlty) different approach: Let F (s) be the function to be inverse-Laplace transformed. Then, F (s) admits the following partial fraction decomposition: F (s) = s−s1A1 + s−s2A2, ... Prove that … WebbAlgebra Solve by Factoring s/ (3s+2)+ (s+3)/ (2s-4)= (-2s)/ (3s^2-4s-4) s 3s + 2 + s + 3 2s - 4 = - 2s 3s2 - 4s - 4 Subtract - 2s 3s2 - 4s - 4 from both sides of the equation. s 3s + 2 + s + 3 2s - 4 - - 2s 3s2 - 4s - 4 = 0 Simplify s 3s + 2 + s + 3 2s - 4 - - 2s 3s2 - 4s - 4.

Solving for the constants yields: A = 3, B = 8, and C = −1. Thus, we get L−1[2s2 + 10s s2 −2s+5 (s+ 1)] = 3L−1[s−1 (s−1)2 + 4] +4L−1[2 (s−1)2 +4] −L−1[1 s +1] = 3ex cos2x+ 4e xsin2x ... in case of active shooter
