How to Use the Roots of Polynomial Calculator

Using the Roots of Polynomial Calculator is a breeze. Follow these simple steps to calculate the roots of your polynomial:

Step 1: Enter the Coefficients

The first step is to input the coefficients of your polynomial. Coefficients are the numerical values that multiply each term in the polynomial expression. For example, in the polynomial equation x3−6×2+11x−6x^3 – 6x^2 + 11x – 6×3−6×2+11x−6, the coefficients are 1, -6, 11, -6.

In the calculator, input the coefficients as comma-separated values in the provided input box. For instance, you would enter 1,-6,11,-6 for the example polynomial x3−6×2+11x−6x^3 – 6x^2 + 11x – 6×3−6×2+11x−6.

Step 2: Click the “Calculate” Button

After entering the coefficients, simply click the Calculate button. The tool will automatically process the coefficients and find the roots of the polynomial using a numerical method, specifically Newton’s Method.

Step 3: View the Results

Once the calculation is completed, the roots of the polynomial will be displayed. The tool will show you all the real roots of the polynomial, which are the values that make the polynomial equal to zero.

Step 4: Reset the Calculator

If you want to perform a new calculation, click the Reset button. This will clear the current inputs and results, allowing you to start fresh.

Example Use Case

Let’s walk through an example to understand how the Roots of Polynomial Calculator works.

Example Polynomial: x3−6×2+11x−6x^3 – 6x^2 + 11x – 6×3−6×2+11x−6

Enter Coefficients: In the input box, enter 1,-6,11,-6.
Calculate: Click the Calculate button.
Result: The calculator will return the roots of the polynomial, such as: Roots: 1,2,3\text{Roots: } 1, 2, 3Roots: 1,2,3 These are the values that make the polynomial equal to zero: x=1x = 1x=1, x=2x = 2x=2, and x=3x = 3x=3.

This is a simple example, but the calculator can handle more complex polynomials as well. The tool is especially useful for higher-degree polynomials, where solving by hand can be very time-consuming.
