The problem and attempt at solution are typed below
The solution of a linear differential equation as yours is the sum of the general solution of the homogeneous part (dP/dt+0.72P=0) and an arbitrary particular solution of the inhomogeneous equation. That solution can be for which dP/dt=0, that is P=const. Find that constant.
The solution of the homogeneous equation is of the form P=a eλt. Find λ.
Thanks ehild, but I think what would help me is if someone could point out the flaws in my original solution. I'm trying to solve this problem using the method taught in class so I'm hesitant to try something that we haven't learned.
I don't see any mistakes in my work.
