Answer :

given: and (1, -2) is a solution

To find: solution of given differential equation

Re-writing the equation as

Integrating both sides


Substituting (-2,1) to find the value of c



2 ln x=y-3 ln (y+3) +2

2 ln x +3 ln (y+3) =y+2

2 ln x +3 ln (y+3) =y+2

ln x2 + ln (y+3)3 =y+2

⇒ x2(y+3)3 = y + c
