x-1 ) x^3 +(0)x^2+(0)x + 1(x^2+x+1
x^3 -x^2
-------------
x^2 +(0)x
x^2 - (1)x

x +1
x - 1

--------------
therefore x^3+1=(x-1)(x^2+x+1) +2
x-1 ) x^3 +(0)x^2+(0)x + 1(x^2+x+1
x^3 -x^2
-------------
x^2 +(0)x
x^2 - (1)x
----------------------
x +1
x - 1

--------------
therefore x^3+1=(x-1)(x^2+x+1) +2
