Answer to Problem 62E
The zeros of the polynomial function are
Explanation of Solution
Given information: The given polynomial function is
From fundamental theorem of algebra we know that every polynomial of degree n has exactly n roots.
So, the given polynomial has exactly 3 roots.
We have the polynomial function is
We know that imaginary roots comes in pair.
i.e if
So,
Now, for the third root we put
This give
Hence, the roots of the polynomial are
