Answer:

Step-by-step explanation:
We have given differential equation 
We know that linear differential equation is given by 
On comparing with standard equation P = -2 and Q= 
Now integrating factor 

Now solution of differential equation is given by




1,4,5,2,3. Division is basically subtraction when it comes to exponents so x to the point of one minus -3 becomes 4, etc.
