Chapter 4: Q. 16 (page 215)

Find the remaining zeros of $f (x)$ with real coefficients and given information.
The degree is 6 and zeros are $i, 3 - 2 i, - 2 + i$

Short Answer

Expert verified

The remaining three zeros of the polynomial are $- i, 3 + 2 i, - 2 - i$ .

Step by step solution

Step 1. Given Information

The polynomial has degree 6 and three zeros are $i, 3 - 2 i, - 2 + i$ .

Step 2. Concept

Conjugate Pair Theorem says that if a polynomial with degree $n$ with real coefficient, has one complex zero of the form $a + i b$ then the polynomial should have the conjugate pair of $a + i b$ that is $a - i b$ as another zero.

Step 3. Explanation

Since the function has coefficients that are real numbers, complex zeros appear as conjugate pairs.

It follows that $- i$ , the conjugate of $i$ , $3 + 2 i$ , the conjugate of $3 - 2 i$ , and $- 2 - i$ , the conjugate of $- 2 + i$ are the remaining three zeros.
