Answer to Problem 79RE
The solution of
Explanation of Solution
Given:
Calculation:
The given function is:
The degree of the given polynomial function is
Now, the values of
Factors of
So the potential rational zeroes are defined as:
Now test the potential rational zeroes with the help of the synthetic division:
If the value of remainder is zero
Here, the remainder is
So, it follows:
So,
Conclusion:
Hence, given function has no complex root.
