ANSWER
We divide x
3
−3x
2
−3x−2 by x
2
−x+1 and if we get the remainder as 0 then it means that x
2
−x+1 is a factor of x
3
−3x
2
−3x−2.
From the above division, we have the quotient x−2 and the remainder is 0.
Hence, x
2
−x+1 is a factor of x
3
−3x
2
−3x−2.

Answer:
Yes it is a factor by factor theorem
Step-by-step explanation:
x-1=0
x = 1
(1)^3-3(1)^2+3-1
1-3+3-1
0
yes it is a factor by using factor theorem
