SUMMARY
The ordinary differential equation (ODE) y' = 2*sqrt(|y|) with the initial condition y(0) = 0 has two distinct solutions around the point (0,0). The first solution is obtained through integration, yielding y(x) = (1/4)x^2, while the second solution is the trivial solution y(x) = 0. The existence and uniqueness theorem confirms that multiple solutions can exist when the function is not Lipschitz continuous at the initial condition, which applies in this case due to the square root term.
