Best ResponseYou've already chosen the best response.1I guess they are defining this polynomial to have real coefficients even though they didn't say that. So when you solve \[ax^2+bx+c=0\] You get \[x=\frac{b \pm \sqrt{b^24ac}}{2a}\]. See of you can use that here. :)

Best ResponseYou've already chosen the best response.1I'm also assuming that this polynomial has a quadratic factor. Such a weird question. Seems incomplete.

Best ResponseYou've already chosen the best response.0That doesn't answer the question either though, cause it's asking what would be another root if one of the polynomial roots is 2+ sqrt(3)

Best ResponseYou've already chosen the best response.1That is 2 general solutions to a general quadratic above.
