    write out a synthetic division table like so 4 | 3 -5 -5 5 2 | -------------------------------------------------- First step is to drop the first coefficient 3 4 | 3 -5 -5 5 2 | -------------------------------------------------- 3 Then multiply that by 4 to get 12. Write this under the first -5 4 | 3 -5 -5 5 2 | 12 -------------------------------------------------- 3 Add the -5 and 12 to get 7 and write it under the 12 4 | 3 -5 -5 5 2 | 12 -------------------------------------------------- 3 7 Repeat the last two steps to get 4 | 3 -5 -5 5 2 | 12 28 -------------------------------------------------- 3 7 23 Keep going until the table is finished

    since 4 is positive and the entire bottom row is positive, this means that 4 is definitely an upper bound of the zeros of f(x).
