This document discusses solving a differential equation of the form (x^2 - 3y^2)dx + 2xydy = 0. It notes that unless the equation is of a special type requiring an integrating factor, the solution involves (1) identifying the type of equation and (2) finding a solution. It then shows the steps to solve this particular equation by making a substitution of y = mx and separating the variables to obtain a variable separable form.
