    indicial roots

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

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

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

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