Rearranging the problem:



 or




Applying direct integration, we denote :






For the left side, we apply the basic integration formula for logarithm:



For the right side, we apply u-substitution by letting then .



 Applying the Power Rule for integration : .



         


Plug-in in , we get:



Combining the results, we get the general solution for differential equation  as:




The general solution: can be expressed as:
