4. Exact different equations cover a large class of interesting non-linear equations that arise in modeling. Since usually we do not have a universally applicable method for solving all these differential equations. It is worth to discover as many fundamental methods as possible by using the basic techniques from Calculus. Now, you are asked to put effort into solving the following equation. (3xy + y) + (x² + xy)y' = 0 (4) (a) First determine whether (4) is exact or not.
