\begin{align*} x^{\prime }&=\frac {3 x t^{2}}{-t^{3}+1} \end{align*}

Solution by Maple

Time used: 0.001 (sec). Leaf size: 13

dsolve(diff(x(t),t)=3*x(t)*t^2/(1-t^3),x(t), singsol=all)
 
\[ x \left (t \right ) = \frac {c_{1}}{t^{3}-1} \]

Solution by Mathematica

Time used: 0.036 (sec). Leaf size: 20

DSolve[D[x[t],t]==3*x[t]*t^2/(1-t^3),x[t],t,IncludeSingularSolutions -> True]
 
\begin{align*} x(t)\to \frac {c_1}{t^3-1} \\ x(t)\to 0 \\ \end{align*}
