SUMMARY
The discussion focuses on solving the homogeneous second-order ordinary differential equation (ODE) given by ax'' + bx' + cx = 0, specifically when the discriminant b² - 4ac = 0. The solution x = e^(kt) is confirmed, where k = -b/(2a). The user successfully substitutes the derivatives of x into the differential equation and simplifies it to demonstrate that the equation holds true, ultimately leading to a cancellation that results in zero.
