comment Why is the particular solution of $y'' - 4y' +3y = e^t$ not in the form of $Ae^t$
"both $e^t$ and $te^t$" meaning the homogenous equation looks like $Ay'' - By' + Cy = e^t + te^t$, then the particular solution will look like $t^2e^t$, am I correct?

and if $te^t$ is already in the homogeneous solution, we will need to multiply by one more $t$ making it $t^2e^t$?
