Better if you know how to do synthetic division, but you can still use polynomial division to find binomial factors according to Rational Roots Theorem. There are a few choices to try for binomial factors, but the successful ones will be (x-2) and (x+2). You will be able to factor the polynomial into this equation:

highlight%28%28x-2%29%28x%2B2%29%28x%5E2-6x%2B1%29=0%29. The roots (or zeros) are +2, -2, 3+2*2^(1/2),
and 3-2*2^(1/2). The non-factorable quadratic factor has irrational roots.
