a) Show that the second order differential equation y'' + (m1 + m2)y' + m1m2y = 0, where m1 and m2 are constants, can be written in the form d/dx(y' + m1y) + m2(y' + m1y) = 0. b) Suppose that m1 = m2 = m. Using the result of (a), solve the first differential equation by solving successively two first order linear equations.

(a) Give a convincing demonstration that the second-order equation $a y^{\prime \prime}+b y^{\prime}+c y=0, a, b,$ and $c$ constants, always possesses at least one solution of the form $y_{1}=e^{m_{1} x}, m_{1}$ constant. (b) Explain why the differential equation in part (a) must then have a second solution either of the form $y_{2}=e^{m_{2} x}$ or of the form $y_{2}=x e^{m_{1} x}, m_{1}$ and $m_{2}$ constants. (c) Reexamine Problems $1-8 .$ Can you explain why the statements in parts (a) and (b) above are not contradicted by the answers to Problems $3-5 ?$
Higher-Order Differential Equations
Reduction of Order
Show that the differential equation obtained from $y=A e^{a x} \cos b x+B e^{a x} \sin b x$ where $A$ and $B$ are arbitrary constants is $y^{\prime \prime}-2 a y^{\prime}+\left(a^{2}+b^{2}\right) y=0$.
Formation of a Differential Equation
Introduction
Second-order linear differential equations take the form $$y^{\prime \prime}(t)+p(t) y^{\prime}(t)+q(t) y(t)=g(t)$$ where $p, q,$ and $g$ are continuous functions of $t .$ Suppose we have initial conditions $y(0)=a$ and $y^{\prime}(0)=b .$ Show that this equation can be rewritten as a system of two first-order linear differential equations having the form $\frac{d \mathbf{x}}{d t}=\left[ \begin{array}{cc}{0} & {1} \\ {-q(t)} & {-p(t)}\end{array}\right] \mathbf{x}+\left[ \begin{array}{c}{0} \\ {g(t)}\end{array}\right]$ $\begin{aligned} \text { with } & \mathbf{x}(0)=\left[ \begin{array}{l}{a} \\ {b}\end{array}\right] \\ \text { where } x_{1}(t)=y(t) \text { and } x_{2}(t) &=y^{\prime}(t) \end{aligned}$
