1. The problem statement, all variables and given/known data

xn+2 − 6xn+1 + 8xn = 2n

Find the particular solution.

3. The attempt at a solution

I've tried "guessing" both xnp = (An + B)*2n and = (Anē + Bn + C)*2n as a solution, but the calculations just don't add up and make sense.

Thanks in advance for any tips and/or hints.
