Hello

I am working on a problem but have found myself stuck and confused as to how t continue...

Thr problem is... Using frobenius mood, seek a solution of Hermite's differential equation

d^{2}y/dx^{2 }-2x dy/dx +2my =0 In the form of a power series

Y(x)= (n=0 n= inf) a_{n}x^{x+r }A_{0 }=/= 0

Im new to this and not very good with the notation...

I have then found y(x), y'(x) and y''(x) and substitute them into the differential equation it is then I can't work out how t rearrange and Solve... Please helppp!!!
