5. [5 points] Solve the differential equation to obtain a complete general solution with arbi- trary constant(s) for y(x). Use method of undetermined coefficients for the particular solution. Show all your steps. day + 2 dy ty = e-" (8) dx2 dx Note: Solving the equation by any other approach is ok only for verifying solution, but you must use the method of undermined coefficient for particular solution to receive any credit
