Not so sure on other root of polynomial, given 3 + 2i is one

Re: Not so sure
There isn't really anything to DO to solve this problem. You just need to remember that if (a + bi) is a root of a polynomial, then (a - bi) is ALSO a root.
Complex roots always occur in conjugate pairs.

Given that x = 3 +2i is a root of a polynomial; name one other root of this polynomial.

Neko san said:Oh. I was thinking of the conjugate <<< only when you are dealing with "real" polynomials - i.e. the coefficients of the polynomial are all real.
but I thought that might be to easy. :lol:
