Ah, I did not pay attention to that. Thank you!

Hi Gerry, it does have a pair of conjugate nonreal eigenvalues: $-1.1726 + 1.0607i, -1.1726 - 1.0607i, 1.1726 + 1.0607i & 1.1726 - 1.0607i$. Do you have a link for a website that has the general solution listed out? I would greatly appreciate it.

So it looks like my matrix A is not diagonalizable (its eigenvalues only have 2 distinct real roots). What are my next steps? $A = [0,1,0,0;-2,0,0,-9/4;-1,0,0,2;0,-2,-1,0]$

Hi Gerry! Can you elaborate please? are you saying that $y=(f,g,h,k)$ is a 1x4 matrix? If so, then $A$ can only be a 1x1 'matrix' and then I'm totally confused.

Thanks to both of you! I have one follow up question: how can I solve this myself?

comment How to solve non-linear system of equations
Ah, I see that now! Thanks for your help. The $\bar{P}$ matrix is as follows: $$\[ \begin{matrix} \bar{P}_{11} & \bar{P}_{12}\\ \bar{P}_{12} & \bar{P}_{22} \end{matrix} \]$$
