Question 120153
Please help me with this problem. I can't seem to figure out how to solve 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

{{{2/3}}} works:

{{{2/3}}}|3  -26  76  -40
  |<u>     2 -16   40</u> 
   3  -24  60    0

Can you finish from there?  If not post again.

Answer: the zeros are  {{{2/3}}}, 4+2i, 4-2i
