A particle moves along the x axis in such a way that it's position at a time is given by: 3t^4-16t^3+24t^2 -55.... How do I find at what time(s) does the particle change direction? I have already found the acceleration and velocity of the particle and at what values of t it is at rest, and the velocity when the acceleration is first zero

A particle moves along the x axis in such a way that it's position at a time is given by: 3t^4-16t^3+24t^2    -5<t>5.... How do I find at what time(s) does the particle change direction? I have already found the acceleration and velocity of the particle and at what values of t it is at rest, and the velocity when the acceleration is first zero
