About Polynomial Root Finder
The Polynomial Root Finder tool helps you find the real roots (x-intercepts) of a polynomial equation. A polynomial equation is an equation of the form \(a_{n} x^{n} + a_{n-1} x^{n-1} + ... + a_1 x + a_0 = 0\), where \(a_{n}, a_{n-1}, ..., a_1, a_0\) are constants and \(n\) is a non-negative integer. The roots of a polynomial equation are the values of \(x\) for which the equation is true. Real roots are the roots that are real numbers, which correspond to the points where the graph of the polynomial intersects the x-axis.
To use this tool, simply enter your polynomial equation in the input field (e.g., x^2 - 4 or x^3 + 2x^2 - x - 2) and click "Find Roots". The tool will calculate and display the real roots and plot the graph of the polynomial, highlighting the roots. You can copy the roots to your clipboard for easy use.
This tool uses the bisection method to numerically approximate the real roots within a specified range. Please note that it may not find all real roots if they are outside the default range or if the polynomial has very closely spaced roots.
