\begin{align*} x^{2} {y^{\prime }}^{2}+x y y^{\prime }-6 y^{2}&=0 \end{align*}

Solution by Maple

Time used: 0.004 (sec). Leaf size: 17

dsolve(x^2*diff(y(x),x)^2+x*y(x)*diff(y(x),x)-6*y(x)^2=0,y(x), singsol=all)
 
\begin{align*} y \left (x \right ) &= c_{1} x^{2} \\ y \left (x \right ) &= \frac {c_{1}}{x^{3}} \\ \end{align*}

Solution by Mathematica

Time used: 0.044 (sec). Leaf size: 26

DSolve[x^2*D[y[x],x]^2+x*y[x]*D[y[x],x]-6*y[x]^2==0,y[x],x,IncludeSingularSolutions -> True]
 
\begin{align*} y(x)\to \frac {c_1}{x^3} \\ y(x)\to c_1 x^2 \\ y(x)\to 0 \\ \end{align*}
