Answer to Problem 124RE
Explanation of Solution
Given information:
Function:
Zero:
Formula used:
To find the zeros of a
Concept used:
Complex zeros occur in conjugate pairs.
Calculation:
The given zero is
Since complex zeros occur in conjugate pairs,
The factor form of the known zeros are
To find the other zeros of the given function, multiply the known factors as follows:
Divide the given function using the quadratic equation obtained by multiplying the known factors.
So, the third factor of the given function is (
Therefore,
Conclusion:
The zeros of the given function are
