Answer 4

How did you get 4 and 8? I was using the factors of 160 and 2. I thought I used four but I did not go to 8 I will try those. I am solving for a polynomial and I am still not able to zero out with plus/minus 4 and 8. Possibly doing it wrong. I will check that website. thanks you

Answer 5

Possible roots by rational root theorem (if doing by hand) are
1,2,4,8,16,32,80 which will produce 4 and 8
