Homework Equations
,The Attempt at a Solution
I envisioned encountering this equation using matrix methods, as outlined in this website, since it was much easier than substitution, differentiation, etc:

However, unlike the method shown in the webpage above, my equation it is a 2nd order DE. Therefore, can I follow the steps exactly as outlined in this example involving only a first order system of DE?
If that is the case, then can I use the same method for the system of DE I wrote below?

This problem is a little bit more different, because it contains a 2nd order AND a first order DE .
Thanks for the continued support!
