\[ \boxed {x^{\prime }-t^{2} x=0} \]

Solution by Maple

Time used: 0.015 (sec). Leaf size: 12

dsolve(diff(x(t),t)=t^2*x(t),x(t), singsol=all)
 

\[ x \left (t \right ) = c_{1} {\mathrm e}^{\frac {t^{3}}{3}} \]

Solution by Mathematica

Time used: 0.041 (sec). Leaf size: 22

DSolve[x'[t]==t^2*x[t],x[t],t,IncludeSingularSolutions -> True]
 

\begin{align*} x(t)\to c_1 e^{\frac {t^3}{3}} x(t)\to 0 \end{align*}
