Thread: Remaining zeros?

Information is given about a complex polynomial f(x) whose coefficients are real numbers. Find the remaining zeros for f.
Degree 3; zeros 1, 2 - i
Can someone explain how to do this?

The other root is .
If a polynomial with real coefficients has a complex root then is also a root.

IM PRISON MIKE! tanks..tanks...but how do you get the answer.
