Answer:

Step-by-step explanation:

Set up synthetic division, starting with x - 1 as the divisor, and then (from that) 1:

1     /    1   0    0    -1               The coefficients of x^2 and x are zero here.

               1     1      1

     --------------------------

         1     1      1      0              

Since the remainder is zero, 1 is a root and x - 1 is a factor of the original

x^3 - 1 = 0.
