Homework Statement
use separation of variables to solve the differential equation x^2dy/dx=y-xy
with the initial condition of y(-1)=-1
Homework Equations
The Attempt at a Solution
after i separated and integrated i got the answer y=e^(-1/x-lnx+c)
the answer in the book is y=e^-(1+1/x)/x
i can't figure out how they got to that even after i plugged in -1 for x and y
some help would be greatly appreciated
