Rational Zeros of the Polynomial Calculator
Introduction & Importance
Rational zeros of a polynomial are the rational numbers that are roots of the polynomial. They play a crucial role in understanding and solving polynomial equations…
How to Use This Calculator
- Enter the polynomial in the ‘Polynomial’ field.
- Choose an interval for the calculation.
- Click ‘Calculate’.
Formula & Methodology
The calculator uses the Rational Root Theorem to find rational zeros. The theorem states that any rational zero of a polynomial with integer coefficients is of the form ±(p/q), where p is a factor of the constant term and q is a factor of the leading coefficient…
