I have a question in my homework that asks me to find the remaining zeros of the polynomial function with: x^2-4x+6 and the final answer has to be in a+bi form, with no decimals... Thanks in advance!!!
You've asked about "the remaining zeros," which would imply that you already have at least one.
Do you have more information than what you've posted here?
Or, are you asked to find the zeroes of x2 - 4x + 6?
If that's the case, then I would suggest using the quadratic formula.
I already have the zero of one that I got from synthetic division but i did the quadratic formula and i got (4+ or -8i)/2 which I reduced to 2+ or -4i and I got it wrong...
Ok....how about if you show us the original problem, and ALL of the work you've done so far to solve it.
I'm generally much better if I know the entire plot....
the question begins by saying list all the rational zeros for x^4-5x^2+10x-6=0 which i did and got correct by putting: 1,-1,2,-2,3,-3,6,-6. Then is says to use synthetic division twice to test the possible rational roots and find two actual roots which I got right when I put 1 and -3. Then it says to now use your quotient from the synthetic division to find the remaining zeros of the polynomial function and the final answer has to be in a+bi form. Thanks!

As far as I understand what you have done the term \(\displaystyle x^2-4x+6\) is supposed to be the result after 2 synthetic divisions by (x - 1) and (x + 3). Right?
This result must be wrong because after dividing by (x + 3) the constant summand of the result must be 2. So check your division first!
