SUMMARY
The discussion focuses on solving second-order differential equations, specifically the equation y'' + ay' + by = g(x). It establishes that if y1 is a solution to this equation, then for any non-zero constant k, the solution to y'' + ay' + by = kg(x) is ky1. Furthermore, it confirms that the general solution to a non-homogeneous linear ODE consists of the complementary function plus a particular integral, leading to the conclusion that the solution to y'' + ay' + by = 3g(x) is 3y1 + y2.
