I see you are using Prime 9. One of the new features of Prime 9 is that it is capable of solving ODE's symbolically.

I suggest you try that, instead of going the Laplace route. If Prime is capable enough, it should be able to give the solution to your ODE as

Where c is a constant.

Prime 9 result:

I want to have also the result with laplace transform (if it is possible)...as a second check

or when:

I find the result interesting.

What number could _z be if it is not part of the set of complex numbers?

 

Success!
