You are given x(t) so just get dx/dt and d2x/dt2 and sub it into the ODE, if the LHS becomes the same as the right side, then it is a solution.

So start by finding dx/dt and d2x/dt2.

ok i started differentiating this and it got really messy but i put what i wrote down into mathtype and this is what i got for x-prime, am i in the right direction?
