I am not sure if I did this right, it is the theorem on bounds to establish integral bounds for roots of equation.

6x^3-7x^2+7x+9=0
1 6 -7 7 9 0 6 -7 7 9
6 -1 6 0 0 0
6 -1 6 15 6 -7 7 9

-1 6 -7 7 9
-6 13 20
6 -13 20 29

answer is -1<x<1

correct
I don't think so, better check it!
Does any know if I am correct? One person said yes, but someone else said no. There was not a reason posted why I was wrong.

Bradley,

Hi presented your question to my online tutoring through my school and the tutor Arjun came back with the response that your answer is correct.

Hope this helps as I am currently having fun:) with this current subject in school as well.

Also to would be helpful if the person who thinks it was wrong would have responded with some suggestions of how to do it different.... but then they also responded with anonymous so there you go....
