Mathematica: cpu = 0.018002 (sec), leaf count = 21 $$\left\{\{y(x)\to \log (2-\frac{e^{c_1}}{2x+1})\}\right\}$$

Maple: cpu = 0.141 (sec), leaf count = 34 $$\{y\left(x\right)=-\ln \left(\frac{2x+1}{-1+4x{\mathrm{e}}^{2\mathit{\_}\mathit{C}\mathit{1}}+2{\mathrm{e}}^{2\mathit{\_}\mathit{C}\mathit{1}}}\right)-2\mathit{\_}\mathit{C}\mathit{1}\}$$
