4. In each case, the possible integral zeros are the factors of the polynomial’s constant term.

   1. The constant term is −8; therefore, the possible integral zeros are as follows:
      
      

       

      ±1, ±2, ±4, ±8

   3. The constant term is 24; therefore, the possible integral zeros are as follows:
      
      
       
      ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24
   5. The constant term is –15; therefore, the possible integral zeros are as follows:
      
      
       
      ±1, ±3, ±5, ±15
