There is not enough information. You can't calculate one root on the basis of another root. HOWEVER, if we assume that all the polynomial's coefficients are real, then if the polynomial has a complex root, then the complex conjugate of that root (in this case, 4 - 17i) must also be a root.

Not that it matters anymore since this was posted so long ago.. but the answer is 4-17i. Not sure why exactly. I just decided that maybe if I were to change the sign to negative, maybe it would work, which it did! Yes, I am smart. No need to thank me.

What polynomial has one root that equals 2 plus i name one other root of this polynomial?
There are infinitely many polynomials which meet the requirement.The polynomial is x2 + (-a - bi - 3)x + (2a - 2bi - ai + b) = 0and the other root is x = a + bi.There is nothing in the question which requires its coefficients to be real.
