SUMMARY
The discussion focuses on solving the equation x^2(yy''-{y'}^2)+xyy'-y\sqrt{y^2+x^2y'^2}=0. A suggested approach involves substituting z=xy', which initially appears ineffective. However, a more effective method is proposed: dividing the equation by y^2 and using the substitution z=y'/y, which simplifies the problem to a first-order equation in z. This technique is crucial for effectively tackling the original equation.
