Use synthetic division to determine which one of the following polynomials is not a factor of the polynomial function: f(x) = x3 – 3x2 – 25x + 75 a.) x+3 b.)

Test (x + 3)

-3  l   1    - 3     -25      75

               -3       18      21

         1    -6       -7       96

So, this is the one that isn't a factor.......(check to see that the other two ARE factors.....)
