Solve \begin {gather*} \boxed {3 y^{2} x^{5}+y^{\prime } x^{3}-2 y^{2}=0} \end {gather*}

Solution by Maple

Time used: 0.0 (sec). Leaf size: 20

dsolve(3*x^5*y(x)^2+x^3*diff(y(x),x) = 2*y(x)^2,y(x), singsol=all)
 

\[ y \relax (x ) = \frac {x^{2}}{x^{5}+c_{1} x^{2}+1} \]

Solution by Mathematica

Time used: 0.146 (sec). Leaf size: 28

DSolve[3*x^5*y[x]^2+x^3*y'[x] == 2*y[x]^2,y[x],x,IncludeSingularSolutions -> True]
 

\begin{align*} y(x)\to \frac {x^2}{x^5-c_1 x^2+1} \\ y(x)\to 0 \\ \end{align*}
