Differential Equations problem

In summary, Differential equations are mathematical equations that describe how a physical quantity changes over time. They are used to solve specific problems involving the behavior of a physical quantity over time. These equations have many real-world applications in fields such as physics, engineering, economics, biology, and chemistry. There are different types of differential equations, including ordinary, partial, and stochastic, which differ based on the number of variables and types of derivatives involved. To solve differential equations problems, various techniques can be used, such as separation of variables, integrating factors, and Laplace transforms. These techniques involve manipulating the equations to isolate the dependent variable and find a solution.

Solving for general solution.


Homework Equations



N/A

The Attempt at a Solution



I have attempted for exactness, have attempted at separating the variables, checked if it was homogeneous, and thrown every method I know at this problem. I am usually excellent with DE, I am at a loss with this problem.

Nevermind, it's homogenous. After you factor out a -y from the first term it becomes more obvious.

Thanks anyway!
