Step 1
If a polynomial function has integer coefficients, then every rational zero will have the form pqpq where pp is a factor of the constant and qq is a factor of the leading coefficient.
p=±1,±3,±9p=±1,±3,±9
q=±1q=±1
Step 2
Find every combination of ±pq±pq. These are the possible roots of the polynomial function.
