How to Use This Calculator
Enter Degree
Input the degree of the polynomial (0-10).
Enter Coefficients
Input coefficients from highest power to lowest power (e.g., for ax² + bx + c, enter a, b, c).
Evaluate (Optional)
Optionally enter an x-value to evaluate the polynomial at that point.
Formula
General form: f(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀
where n is the degree and aₙ, aₙ₋₁, ..., a₁, a₀ are coefficients
Example: Degree 2, coefficients [1, -3, 2] gives f(x) = x² - 3x + 2
At x = 2: f(2) = 2² - 3(2) + 2 = 4 - 6 + 2 = 0

Frequently Asked Questions
What is a polynomial?
A polynomial is an expression of the form f(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀, where n is a non-negative integer and a₀, a₁, ..., aₙ are coefficients. Examples: x² + 3x - 2 (degree 2), 5x³ - x + 1 (degree 3).
How do I enter coefficients?
Enter coefficients from highest power to lowest. For example, for x² + 3x - 2, enter coefficient of x²: 1, coefficient of x: 3, constant: -2.
