WebDec 15, 2015 · The fundamental theorem of algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number is a complex number with an imaginary part equal to zero. Webwe illustrate the technique by solving a variety of higher-degree polynomial equations, with real and complex coefficients, and with real and complex roots. Graphing relations For purposes of the present study, we introduce a simple notational device: all polynomial equations are henceforth to be written in terms of the variable z.
