Mathematica: cpu = 0.124516 (sec), leaf count = 111 $$\left\{\{y(x)\to \frac{x(-2e^{\sqrt{2}{c}_1+\frac{\sqrt{2}{x}^3}{3}}+e^{2\sqrt{2}{c}_1+\frac{2\sqrt{2}{x}^3}{3}}-1)}{2e^{\sqrt{2}{c}_1+\frac{\sqrt{2}{x}^3}{3}}+e^{2\sqrt{2}{c}_1+\frac{2\sqrt{2}{x}^3}{3}}-1}\}\right\}$$

Maple: cpu = 0.156 (sec), leaf count = 49 $$\{\ln \left(2\frac{x(\sqrt{2{\left(y\left(x\right)\right)}^2+2x^2}+y\left(x\right)+x)}{y\left(x\right)-x}\right)+\frac{\sqrt{2}{x}^3}{3}-\ln \left(x\right)-\mathit{\_}\mathit{C}\mathit{1}=0\}$$
