Answer 4

Putting it to wolfram is a poor advice and again not at all insightful.

Use rational root test to find the first root x=3 is a root and then use synthetic division or ruffini's rule to get the final answer.

you can also use long division.

The answer you will get is that the zeros will be at \( \pm 4\) and \( 3 \)
