Iv'e got an exam in like 2 weeks and i don't have any material on how to do this question so i know the forum says i should make an attempt at the question but i really don't have a clue where to start could someone run me through it please so i will be able to answer it and others like it in the exam thanks

find the general soultion of the equation
x²y'=y²+3xy+x²

Dividing the equation by x^2 will give you a form of a DE which should be recognisable.
