Calculateur de polynômes

Évaluez une expression polynomiale pour une valeur de x donnée.

Introduction

Polynomial Calculator — Evaluate a polynomial expression at a given x value. Enter Coefficients (highest degree first, comma separated), x to get an instant, accurate result.

Formule

Evaluates a polynomial at a given x using Horner's method: coefficients (highest degree first) are combined as result = result×x + coefficient, working left to right.

Étape par étape

  1. Enter the Coefficients (highest degree first, comma separated).
  2. Enter the x.
  3. Click Calculate to see your result instantly.

Exemple concret

Example: With Coefficients (highest degree first, comma separated) = 1, -3, 2, x = 2, the Polynomial Calculator gives Result: 0.

Questions Fréquentes

In what order do I enter the coefficients?
Highest degree term first, down to the constant term.
What is Horner's method?
An efficient way to evaluate a polynomial that avoids separately computing each power of x.
What inputs does the Polynomial Calculator need?
You'll need to provide: Coefficients (highest degree first, comma separated), x. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Polynomial Calculator?
The Polynomial Calculator applies the formula exactly as calculated — Evaluates a polynomial at a given x using Horner's method: coefficients (highest degree first) are combined as result = result×x + coefficient, working left to right. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Polynomial Calculator free to use?
Yes, the Polynomial Calculator is completely free, requires no signup, and runs instantly in your browser.

À propos de Calculateur de polynômes

The Polynomial Calculator uses a real, verifiable formula — Evaluates a polynomial at a given x using Horner's method: coefficients (highest degree first) are combined as result = result×x + coefficient, working left to right. — so results are accurate every time, not an approximation.
