Answer:
see explanation
Step-by-step explanation:
radical zeros occur as conjugate pairs, thus
[tex]\sqrt{3}[/tex] is a zero then - [tex]\sqrt{3}[/tex] is also a zero
3 + [tex]\sqrt{6}[/tex] is a zero then 3 - [tex]\sqrt{6}[/tex] is also a zero
The additional zeros are
- [tex]\sqrt{3}[/tex] , 3 - [tex]\sqrt{6}[/tex]
