Answer:

Step-by-step explanation:
We want to find a third degree polynomial with zeros <em>x </em>= 2 and <em>x</em> = 2i and f(-1) = 30. 
First, note that by the Complex Root Theorem, since <em>x</em> = 2i is a root, <em>x</em> = -2i must also be a root. 
Hence, we will have the three factors: 

Where <em>a</em> is the leading coefficient. 
Expand and simplify the second and third factors:

Hence: 

Since f(-1) = 30: 

In conclusion, third degree polynomial function is:
