Find the general solution of the linear ODE y prime + y = sqrt(x) e^(-x).

Question:

Find the general solution of the linear ODE {eq}\; {y}' + y = \sqrt{x} \, e^{-x} {/eq}.

First Order Linear Differential Equations

These are the differential equation in the form

{eq}y' + P(x)y = Q(x) {/eq}

This is solved by getting an integration factor through the equation:

{eq}I = e^{\int P(x)\;dx} {/eq}

This is multiplied to the differential equation, then integrate the whole equation to solve.
