Information is given about a polynominal f(x) whose coefficients are real numbers. Find the remaing zeros of f.

Degree 3; zeros: 2, -5-i

Enter the remaining zeros of f.

Solution:

f(x) has a degree of 3, so it has 3 zeros, one real zeros, 2 imaginary zeros which are conjugate

so the remaining zeros of f is -5+i
