\begin{align*} y^{\prime }&=t^{2}+t \end{align*}

✓ Solution by Maple

Time used: 0.001 (sec). Leaf size: 16

dsolve(diff(y(t),t)=t^2+t,y(t), singsol=all)
 

\[ y = \frac {1}{3} t^{3}+\frac {1}{2} t^{2}+c_{1} \]

✓ Solution by Mathematica

Time used: 0.002 (sec). Leaf size: 22

DSolve[D[y[t],t]==t^2+t,y[t],t,IncludeSingularSolutions -> True]
 

\[ y(t)\to \frac {t^3}{3}+\frac {t^2}{2}+c_1 \]
