3. Maple input

Mathematica: cpu = 125.836479 (sec), leaf count = 37 $$\text{DSolve}[-\text{f0}(x)-\text{f1}(x)y(x)-\text{f2}(x)y(x{)}^2-\text{f3}(x)y(x{)}^3+y^{\prime }(x)=0,y(x),x]$$

Maple: cpu = 0.265 (sec), leaf count = 0 $$\text{could not solve}$$

Sage: cpu = 0 (sec), leaf count = 0 $$\text{Maxima was unable to solve this ODE}$$
