Write all real and imaginary zeros.
f(x)=x^3-8x^2+x-8
-8--1,-2,-4,-8
1
-+1,-+2,-+4,-+8
1-8 1-8
1
1-7-6
1 -7 -6 -14
2 1 -8 1 -8
2 -12 -22
1 -6 -11 -30
4 1 -8 1 -8
4 -16 -60
1 -4 -15 -52
answer (?) 8 is zero of f(x)
8 1 -8 1 -8
8 0 8
1 0 10
If your answer is 8 is zero of f(x), no
we had this problem and that is not the answer if I remember
