\

The degree of $\"\"$ is $\"\"$ , the zeros are $\"\"$ and $\"\"$ .

\

Since the degree of the polynomial is $\"\"$ , the zeros of $\"\"$ are $\"\"$ .

\

From the conjugate pair theorem, complex zeros occur in conjugate pairs.

\

Conjugate of $\"\"$ is $\"\"$ .

\

Conjugate of $\"\"$ is $\"\"$ .

\

The five zeros are $\"\"$ , $\"\"$ , $\"\"$ and $\"\"$ .

\

$\"\"$

\

If $\"\"$ are the zeros of the polynomial $\"\"$ , then the polynomial function can be written as $\"\"$ , where $\"\"$ is the leading coefficient of the polynomial.

\

Consider the leading coefficient $\"\"$ as $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Hence, the polynomial function is $\"\"$ and $\"\"$ .

\

$\"\"$

\

The polynomial function is $\"\"$ and $\"\"$ .
