Use the given zero to find all the zeros of the function. Function Zero X³ + 13x² + 59x + 87 -5 - 2i A)3,5 ± 2i B)±3i,-5 ± 2i C)-3,5 ± 2i D)-3,-5 ± 2i E)3,-5 ± 2i

Question

Quizplus · Accepted Answer

Since the coefficients of the polynomial are real, complex zeros occur in conjugate pairs. Given -5 - 2i is a zero, its conjugate -5 + 2i is also a zero. Using synthetic division or factoring, the remaining zero is found to be -3.
