Given One Zero or Factor Find the Remaining Zeros

The video tutorial explains how to find the remaining zeros of a polynomial when one zero is a complex number, specifically 2i. The instructor demonstrates using synthetic division to handle complex zeros and shows that if 2i is a zero, then -2i must also be a zero. The process involves performing synthetic division twice, first with 2i and then with -2i, to simplify the polynomial and find the remaining zeros. The final zeros identified are 2i, -2i, 1, and -1/2. The tutorial emphasizes that synthetic division can be used effectively with complex numbers.

Describe the final remaining equation after performing synthetic division.

List all the zeros of the polynomial as mentioned in the text.
