Well, the way I showed to you works, but that polyomial you provided has no rational roots, so if you want the results

Order of Polynomial, n = 3

The Coefficients are:
a[0] = -1
a[1] = 8
a[2] = -1
a[3] = 6

The Normalized Coefficients are:
a[0] = 1.00000000000000
a[1] = -8
a[2] = 1
a[3] = -6

The Roots are:
