There are two questions that I am trying to solve on web assignment. The goal is to find a general form of a particular solution to each ODE. The question asks me to represent all constants in the solution using "P,Q,R,S,T..etc.", in that order.
1. y'''-9y''+14y'=x2
2. y''-9y'+14y=x2e4x
For the first one I wrote:
yp=Px3+Qx2+Rx
Second one:
yp=(Px2+Qx+R)e4x
Neither of the answers are correct, according to the computer. Where did I go wrong?
Thanks.
