Question 120153: Please help me with this problem. I can't seem to figure out how to slove it.
Find all the zeros of each function by using synthetic division.
f(x)=3x^3-26x^2+76x-40
---I did the p/q hing to help me out, but none of them seemed to work unless I made a math error (but I would have had to do the same mistake because I did some of them twice).---
Thank You
