Step 1:

The polynomial function is $\"\"$ .

Use rational zero theorem to find the potential rational zeros of a polynomial function.

If $\"\"$ is the rational zero, then $\"\"$ is factor of the constant term $\"\"$ and $\"\"$ is factor of the leading coefficient $\"\"$ .

The possible values of $\"\"$ are $\"\"$ .

Now form all possible ratios of $\"\"$ are $\"\"$ .

Solution :

The potential rational zeros are $\"\"$ .
