1. ## indicial roots

ok in this problem, im supposed to find the indicial roots and determine whether or not they differ by an integer..

$2x^{2}y''-6xy'+(x^{2}+4)y=0$

i got the roots, $2\pm \sqrt{2}$

and said that they do not differ by an integer...so did i do the problem right?

Yes your indicial roots are correct.
