The answer I got from this problem is 11 :(
if the roots of the polynomial function are -9 and 7 - i, then the other factor of the polynomial function is x - (7 + i)
<h3>How to determine the other factor?</h3>
The roots of the polynomial function are given as:
-9 and 7 - i
The root is 7 - i is a complex number.
This means that its conjugate must also be a root of the factor.
The conjugate of 7 - i is 7 + i
So, we have:
x = 7 + i
Equate to 0
x - (7 + i) = 0
Hence, the other factor of the function is x - (7 + i)

It is 8 bc you count them then you use pythagorean theorem
