@Idealist hey girl!! you should post the original one to get help. Don't post just the part you don't understand or get stuck. I guess it comes from ODE and relate to laplace transform or something like that. Other is characteristic equation from a 2x2 matrix and you need that factor to get eigenvalue. 
One more thing, the equation you gave out lead to complex solution which is not eigenvalues of the matrix $\rightarrow$ I think you make mistake at somewhere.
