Question

Can we conclude that x - 4 is a factor of the polynomial 4x^3-20x^2+18x-12?
How do you know?

Answer 1

Answer:

The answer to your question is: x - 4 is not a factor

Step-by-step explanation:

x - 4 is a factor of    4x³ - 20x² + 18x -12

We can do synthetic division to know if it is a factor

                           4     - 20     +18      -12         4

                                     16      -16        8                                              

                           4       -4         +2     -4

x -4  is not a factor because there was a residue of -4
