I was doing supplemental problem A and found:
$ e^{-2t}(2A-2At^2+4At-3)=0. $
So if t=0 then A=3/2 And: $ e^{-2t}(-4Bt+4B-3)=0. $
So if t=0 then B=4/3
But with the variable t I wasn't sure if these answers were enough for A and B or if I needed to find more possibilities, which I had no clue how to do.
