Answer:
the correct answer for that would be identity property 
 
        
                    
             
        
        
        
Answer: 1 to 8
Reason: because there’s 1 of 8 items is the same ratio
        
             
        
        
        
Write the coeeficientes of the polynomial in order:
  | 1   - 5   6   - 30
  |
  |
  |
------------------------
After some trials you probe with 5
   | 1   - 5       6     - 30
   |
   |
5 |        5      0       30
-----------------------------
     1     0      6        0 <---- residue
Given that the residue is 0, 5 is a root.
The quotient is x^2 + 6 = 0, which does not have a real root.
Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.
