1. Problem in Latex
2. Mathematica input
3. Maple input

Mathematica: cpu = 0.003000 (sec), leaf count = 24 $$\left\{\{y(x)\to c_4{x}^3+c_3{x}^2+c_{2}x+c_1\}\right\}$$

Maple: cpu = 0.141 (sec), leaf count = 21 $$\{y\left(x\right)=\frac{\mathit{\_}\mathit{C}\mathit{1}{x}^3}{6}+\frac{\mathit{\_}\mathit{C}\mathit{2}{x}^2}{2}+\mathit{\_}\mathit{C}\mathit{3}x+\mathit{\_}\mathit{C}\mathit{4}\}$$
