Finding Factors and Zeros of Polynomials Calculator
Introduction & Importance
Finding factors and zeros of polynomials is a crucial aspect of algebra, with wide-ranging applications in mathematics, physics, engineering, and more. This calculator helps you understand and apply these concepts with ease.
How to Use This Calculator
- Enter a polynomial in the format ‘ax^n + bx^(n-1) + … + cx^1 + d’.
- Enter the interval for which you want to find the factors and zeros.
- Click ‘Calculate’.
Formula & Methodology
The calculator uses the Rational Root Theorem to find the potential rational roots (zeros) of the polynomial. It then uses these roots to factor the polynomial.
