Let's begin by solving the given second-order linear differential equation for the particular solution of the form \( y = e^{mx} \). The general differential equation is: \[ \frac{d^2y}{dx^2} + a(x)\frac{dy}{dx} + b(x)y = 0 \] We are asked to show that \( e^{mx} \) is a particular solution when \( m^2 + a(m) + b(m) = 0 \), where \( a(x) \) and \( b(x) \) are functions of \( x \). ### Step 1: Substituting \( y = e^{mx} \) into the differential equation For the equation \( y = e^{mx} \), the first and second derivatives ____ _______ ________ ____ ____ _________ _________ ________ _____ ___ ___ __________.
