... The characteristic polynomial is r 2 − 6r + 25, which has roots 3 ± 4i (via the quadratic equation). Thus the general solution is y(x) = c1 e3x cos(4x) + c2 e3x sin(4x). 3. Find a particular solution: y (3) − 4y ′ = 3x − 1. The characteristic polynomial is r 3 −4r, which factors as r(r+2)(r− 2), and ...
