Your possible values to check according to Rational Roots Theorem with synthetic division are PLUS AND MINUS OF these: { 5/3, 1/3, 5, 3, 1 }.

Greatly abbreviating the process here, You may find something about like this:
Checking 5, remainder 0, quotient .
Checking -3, remainder 0, quotient .

The polynomial in factored form is .
The next zero based on the last binomial factor is +, so the three roots or zeros are , , .

These are all Real zeros. They are also Complex zeros for which the imaginary compenents are zero.
