1. The problem statement, all variables and given/known data Hello all, I have a quick question, I'm solving a d.e using the Frobenius method and I have the indicial equation: C1(2r-1)(r-1)+C2x(r)(2r+1)=0 Where c1 and c2 are arbitrary constants not equal to zero. 2. Relevant equations 3. The attempt at a solution My question is, what are the roots? Previously I had only one constant and I would just leave it out since it's not equal to zero. Know that I have 2 constants can I just get rid of both of them? I need to solve for the r that makes the above statement true. Any help? Thanks!
