## Homework Statement

find general solution of

dy/dx=xy+x

using integrating factor

## Homework Equations

## The Attempt at a Solution

rearange

dy/dx-xy=x

take integrating factor as

e^int(-x)=e^-(x^2)/2

multiply throughout

dy/dx(e^-(x^2)/2)y=(e^-(x^2)/2)x

integrate

e^-(x^2)/2*y=int (e^-(x^2)/2)*x dx

dont know how to integrate (e^-(x^2)/2)*x

cheers
