$$y^{\prime }(x)=\frac{x^3\sqrt{x^2+y(x{)}^2}+y(x)}{x}$$ ✓ Mathematica : cpu = 0.10053 (sec), leaf count = 20

$$\left\{\{y(x)\to x\sinh \left(\frac{1}{3}(x^3+3c_1)\right)\}\right\}$$ ✓ Maple : cpu = 5.813 (sec), leaf count = 30

$$\{\ln (\sqrt{{\left(y\left(x\right)\right)}^2+x^2}+y\left(x\right))-\frac{x^3}{3}-\ln \left(x\right)-\mathit{\_}\mathit{C}\mathit{1}=0\}$$
