Question

Find the remaining zeros of f
Degree 4; zeros: 8i, 6, -6
The reaming zeros of f are ?

Answer 1

- 8i

Explanation:

the Fundamental theorem of algebra states that

A polynomial of degree n has n roots, some may be complex

• Complex roots occur as conjugate pairs

For this polynomial of degree 4, there are 4 zeros

given 8i , 6 , - 6 , then the fourth root is the conjugate of 8i , that is - 8i
