1. The problem statement, all variables and given/known data Solve DE: y' -2 y / (x + a) = -1 where a = constant 2. Relevant equations y' + p(x) y = q(x) solving this DE with integrating factor. 3. The attempt at a solution Use integrating factor (x+a) ^ -2 for above DE, [ y'(x+a) ^ -2 ]' = - (x+a)^ -2 solving this DE we get y = C(x+a)^2 + (x+a) this seems to be a solution, C = arbitrary constant Is this the only solution??
