The calculator extracts square factors from the input polynomial.

The calculators isolates real roots of the input univariate polynomial using Sturm and VAS-CF methods.

The calculator solves polynomial roots of any degree. For small degree polynomials analytic methods are applied, for 5-degree or higher the polynomial roots are estimated by numerical method.

This online calculator allows you to use completing the square technique to complete the square.

The calculator finds all factors of a polynomial with rational coefficients

This online calculator builds a regression model to fit a curve using the linear least squares method. If additional constraints on the approximating function are entered, the calculator uses Lagrange multipliers to find the solutions.
