Given that  $x=1$   zero of the function
 $f\left(x\right)=x^3-9x^2+2x+6$  
 use synthetic division to help you find all of the other zeros. All solutions must be exact - no approximate answers.

•  $x=4\pm i\sqrt{10}$  

•  $x=4\pm i\sqrt{22}$  

•  $x=4\pm\sqrt{22}$  

•  $x=-4\pm\sqrt{22}$  

•  $x=-4\pm i\sqrt{10}$
