Find roots of this polynomial?
OK, so I have a polynomial that looks like:
3x^8+6x^7-136x^6-2x^5+42x^4-6x^3+136x^2+2x-45=0.
So I have already done Descartes Rule of Signs, and my Positive, Negative, Complex chart ended up looking like this:

+,-,C
   5            3             0
   3            3             2
   1            3             4
   3            1             4
   5            1             2
Also given it says that 1 of the roots is -1+radical46.
Is there any way to find the rest of the roots? 
================
Try the factors of 45.
1, 3, 5, 9, 15  plus and minus.
