Question

Information is given about a polynomial f(x) whose coefficients are real

numbers. Find the remaining zeros of f.

Degree 3; zeros: -4, -2- i

The remaining zero(s) of f is
(Use a comma to separate answers as needed.)

Answer 1

Answer: -2+i

Explanation:

By the conjugate root theorem, since the coefficients are real, the complex conjugate of a root must also be a root.
