Polynomials Calculator
Evaluate, differentiate, and solve polynomial expressions up to degree four. Enter the coefficients, choose a value of x, and instantly see roots, degree, leading term, and a visual graph.
Choose a linear, quadratic, cubic, or quartic polynomial.
Fill in each coefficient and the x-value to evaluate.
See the value, derivative, roots, equation, and graph.
The calculator evaluates the polynomial using Horner’s method, differentiates each term using the power rule, and estimates polynomial roots numerically.
Use this calculator for algebra homework, graph analysis, engineering models, curve fitting, economics, physics equations, optimization, root checking, and calculus preparation.
Coefficients must be finite numbers and the leading coefficient cannot be zero. Numerical roots may contain very small rounding differences.
What can this polynomial calculator do?
It evaluates a polynomial, finds its derivative, estimates roots, identifies its degree, and draws a quick graph.
Can it solve cubic and quartic polynomials?
Yes. Select degree three or four and enter the required coefficients.
What is a complex root?
A complex root contains an imaginary component and does not appear as a normal x-axis crossing on a real graph.
