I know if -3 + i is zero, then (x - (-3 + i)) and (x - (-3 - i)) are factors. I multiplied those together to get x^2 + 6x + 1. I used long division to divide the original function by x^2 + 6x + 1, but that did not help. I also made a rational zero list and did synthetic division with the hope of finding a zero, but I could not find a zero by that method too. Could someone help me? EDIT: Please disregard this thread. I made an error when using synthetic division with 1/4 as the possible zero. Thus, 1/4 is the other zero along with the two mentioned above. >_< Last edited by Pathos; 01-06-2011 at 06:44 PM.
