Show all work. How you get your answer is just
as important, if not more important, than the
answer itself. If you think it, write it!
has, as one solution, the function y = x. Use reduction of order to find a second, linearly independent, solution.
has solutions y1 = x-1 and y2 = x-2. Use variation of parameters to find a particular solution to the inhomogeneous equation
Missing: solutions to higher order, constant coefficients, equation
