Solution by Maple

Time used: 0.062 (sec). Leaf size: 16

dsolve([diff(y(x),x) = 2*y(x)^2+x*y(x)^2,y(0) = 1],y(x), singsol=all)
 
\[ y = -\frac {2}{x^{2}+4 x -2} \]

Solution by Mathematica

Time used: 0.140 (sec). Leaf size: 17

DSolve[{D[y[x],x] == 2*y[x]^2+x*y[x]^2,y[0]==1},y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to -\frac {2}{x^2+4 x-2} \]
