1. The problem statement, all variables and given/known data Solve the following initial-value problem, using variation of parameters.: 2y'' + y' - y = x + 1; y(0) = 1, y'(0) = 0 2. Relevant equations Variation of parameters: u_n' `=` W_n/W 3. The attempt at a solution I'm posting this thread, because I'm getting a wrong particular solution (according to Wolfram Alpha), and I can't find the mistake after reviewing my work numerous times. It doesn't matter which column, I put the fundamental set of solutions (from the complementary solution), right? My (typed) work is attached as MyWork.pdf. Any help in finding my mistake(s) would be greatly appreciated!
