My book says V=dx/dt=B+3Ct^2 when x=A+Bt+Ct^3. This doesn't make any sense to me? Could anybody explain how x/t turned into B+3Ct^2 ?(adsbygoogle = window.adsbygoogle || []).push({});

a=dV/dt=6Ct How can V/t turn into 6Ct ? I don't understand this either :( If anobody could explain this would help me really really much.
