I don't know what you're talking about,
and I suspect you don't, either.

Asking how to solve d^2x/dt^2
is a little like asking how to solve x.
It makes no sense.
One solves equations, not expressions, and d^2x/dt^2 is not an equation.

What is the full statement of the problem you are trying to solve?
