 Polynomial Equations Packed into functions like Solve and Reduce are a wealth of sophisticated algorithms, many created specifically for Mathematica. Routinely handling both dense and sparse polynomials with thousands of terms, Mathematica can represent results in terms of numerical approximations, exact radicals or its unique symbolic Root object constructs. Solve — find generic solutions Roots — roots of a univariate polynomial Reduce — reduce a general polynomial system Solutions in Radicals Root Isolation CountRoots — count roots in an interval Numerical Approximations TUTORIALS Solving Equations Algebraic Operations on Polynomials Structural Operations on Polynomials Polynomials Modulo Primes Polynomials over Algebraic Number Fields Counting and Isolating Polynomial Roots Numerical Solution of Polynomial Equations MORE ABOUT Polynomial Systems Algebraic Numbers Algebraic Number Fields RELATED LINKS Demonstrations related to Polynomial Equations (The Wolfram Demonstrations Project)
