The possible rational zeros of
\ =\ a_0x^n\ +\ a_1x^{n-1}\ +\ \cdots\ +\ a_{n-1}x\ +\ a_n)
are elements of the set 
So, for
\ =\ x^3\ -\ x^2\ -\ 8x\ -\ 2)
, 
. The only integer divisors of 1 are 
, and the only integer divisors of 2 are and 
so the possible rational roots are and
Use synthetic division to test each of the possibilities, since the synthetic division remainder for an 
divisor is equal to )
