Answer:
All potential roots are 3,3 and
.
Step-by-step explanation:
Potential roots of the polynomial is all possible roots of f(x).

Using rational root theorem test. We will find all the possible or potential roots of the polynomial.
p=All the positive/negative factors of 45
q=All the positive/negative factors of 3


All possible roots

Now we check each rational root and see which are possible roots for given function.




Similarly, we will check for all value of p/q and we get

Thus, All potential roots are 3,3 and
.
