Find rational roots of a polynomial up to degree 6 using the rational root theorem.
The Rational Root Theorem states that any rational root p/q of a polynomial with integer coefficients must have p dividing the constant term and q dividing the leading coefficient. This calculator tests all such candidates and deflates the polynomial via synthetic division when a root is found.
Rational Root Theorem
Candidates: ±(factors of constant term) / (factors of leading coefficient)
This calculator only finds rational roots. Irrational or complex roots will not be detected — use the cubic or quartic solver for those.
Enter comma-separated numbers from the highest degree to the lowest. For x³−6x²+11x−6, enter 1,-6,11,-6.
