Answer:
Step-by-step explanation:
See comment for complete question.
From the complete question, we have:
Required
Determine the other zero
The zeros can be represented as:
Considering the 3rd zero, which is a complex number.
If a polynomial has a complex number as one of its zeros, then its conjugate pair is the corresponding zero
A conjugate pair is given as:
and
For
The conjugate pair is:
Hence, the other zero is:
