1. The problem statement, all variables and given/known data Find a particular solution Yp of the given equation. Primes denote deriviate with respect to x (method of flexible guess) 2. Relevant equations 4y''+4y'+y=3xe^x 3. The attempt at a solution when I used y=Ae^x as guess my A depended on x So y=Axe^x gave me 12A+9Ax=3x 12A=0 9Ax=3x does not work, Before I go on to trying y=Ax^2e^x am I doing this right?
