Find the general solution for the given equation
Solution:
Consider the given equation
Check if the given equation is exact or not exact as follows
Let
Let
Since
The given equation is not an exact equation. In this case, we need to find the integrating factor and then multiply it to the both sides of the equation. Let's consider again the given equation
Arrange the above equation into its standard form as follows
Divide both sides of the equation by dx
Divide both sides of the equation by (x + 1)2
As you notice that the above equation is now already in standard form
where
and
The integrating factor is
Therefore, the general solution for the above equation is
