I HAVE Done this problem so many times my answers seem to be right but idk why theyre wrong

Problem 10 (1 point) Previous Problem Problem List Next Problem Match the following guess solutions Up for the method of undetermined coefficients with the second-order nonhomogeneous linear equations below. A. Up(x) = Ax + Bac + C B. Up (a) = Ae2x C. Up (a) = A cos 2x + Bsin 2x D. Up(x) = (Ax + B) cos 2x + (Cx + D) sin 2x E. Up(a) = Axelx, F. Up (x) = es ( A cos 2x + B sin 2x) 1. E 5- dy + 6y = e2 20 da 2 dx day 2. A + 4y = -3x2 + 2x +3 da-2 3. C y" + 4y + 13y = 3 cos 2x 4. F y" - 2y - 15y = 3x cos 2x Note: In order to get credit for this problem all answers must be correct.
