The differential equation
(dy)/(dx)=9+27x+15y+45xy
has an implicit general solution of the form
F(x,y)=K
. In fact, because the differential equation is separable, we can define the solution curve implicitly by a function in the form
F(x,y)=G(x)+H(y)=K
Find such a solution and then give the related functions requested.
F(x,y)=G(x)+H(y)=
