Free Expand Master and Build Polynomial Equations Calculator - This calculator is the ultimate expansion tool to multiply polynomials. It expands algebraic expressions listed below using all 26 variables (a-z) as well as negative powers to handle polynomial multiplication. Includes multiple variable expressions as well as outside multipliers. Also produces a polynomial equation from a given set of roots (polynomial zeros). * Binomial Expansions c(a + b)x * Polynomial Expansions c(d + e + f)x * FOIL Expansions (a + b)(c + d) * Multiple Parentheses Multiplications c(a + b)(d + e)(f + g)(h + i)
