Question

ODE question to follow......

Answer 1

I have a power series substitution which I need to simplify to \[L[y(x,r)]=x^r(r-r_1)^2\]I've got as far as\[L[y(x,r)]=\sum_{n=0}^{\infty}(c_n(r)(n+r)(n+r-1)+\sum_{k=0}^{n}(p_{n-k}(k+r)+q_{n-k})c_k(r))x^{n+r}\]Can anyone please help with this simplification? Thanks.
