\begin{align*} y^{\prime }&=1+x^{2}+y^{2}+x^{2} y^{2} \end{align*}

Solution by Maple

Time used: 0.004 (sec). Leaf size: 13

dsolve(diff(y(x),x)=1+x^2+y(x)^2+x^2*y(x)^2,y(x), singsol=all)
 
\[ y = \tan \left (\frac {1}{3} x^{3}+x +c_1 \right ) \]

Solution by Mathematica

Time used: 0.215 (sec). Leaf size: 17

DSolve[D[y[x],x]==1+x^2+y[x]^2+x^2*y[x]^2,y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \tan \left (\frac {x^3}{3}+x+c_1\right ) \]
