I need help on solving this. Our professor requires that we must use this format:
W=u' and W'=u"
Picture of it is down below.
I do not know what to do once I have W'=0 my integrating factor would be weird

Because W'=0. Therefore, that means my int. factor is e^(integral of 0) which = e^c.
so then we times the integrating factor by the whole equation....
then d/dx [e^c*W]=0
integrate.
W=c1*e^(-c)
W=u'... we need to find u because y=uy1
therefore...
integral of W...=?
I just feel like I am doing this wrong.
The solution to y_2= xe^2x
