## Homework Statement

[/B]

## Homework Equations

##W(x) = C exp (∫ P(x) dx)##

##y''+P(x)y'+g(x)=0##

## The Attempt at a Solution

Divide the origin equation by (x) to get the standard form of the homogeneous equation :

##y'' +\frac{3y'}{x} - \frac{3y}{x}##

##P(x) = \frac{3}{x}##

## exp (- ∫ \frac{3}{x}##

## = exp ( -3 ln (x))##

## = x^{-3}##

##W(x) = C x^{-3} ##

Could someone check my answer please?
