\[ \boxed {{\mathrm e}^{2 x} y^{2}+\left (y \,{\mathrm e}^{2 x}-2 y\right ) y^{\prime }=0} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 58

dsolve((exp(2*x)*y(x)^2)+(exp(2*x)*y(x)-2*y(x))*diff(y(x),x)=0,y(x), singsol=all)
 

\begin{align*} y \left (x \right ) &= 0 \\ y \left (x \right ) &= \frac {\sqrt {2}\, \sqrt {-\left ({\mathrm e}^{2 x}-2\right ) c_{1}}}{{\mathrm e}^{2 x}-2} \\ y \left (x \right ) &= -\frac {\sqrt {2}\, \sqrt {-\left ({\mathrm e}^{2 x}-2\right ) c_{1}}}{{\mathrm e}^{2 x}-2} \\ \end{align*}
