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

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

From the Conjugate pairs theorem, complex zeros appear as conjugate pairs.

Conjugate of $\"\"$ is $\"\"$ , conjugate of $\"\"$ is $\"\"$ and conjugate of $\"\"$ is $\"\"$ .

Therefore, the remaining zeros are $\"\"$ , $\"\"$ and $\"\"$ .

The remaining zeros of $\"\"$ are $\"\"$ , $\"\"$ and $\"\"$ .
