Material in this section comes from Section of the textbookThe Rational Roots Test The Rational Roots Test (called the Rational Zero Theorem by the book) is a tool that can help us to nd the x-intercepts, or roots of any polynomial. ProblemFinish the proof of the Fundamental Theorem of Algebra, by  The fundamental theorem of algebra, also called d'Alembert's theorem or the d'Alembert–Gauss theorem, states that every non-constant single-variable polynomial  Theorem (Fundamental Theorem of Algebra). which will allow us to state the Fundamental Theorem of Algebra. a1x + a0 =is a polynomial equation in the unknown coefficients an 1,,  Theorem (Rouche). Material in this section comes from Section of the textbookThe Rational Roots Test The Rational  TheoremFor every polynomial f, there is a point zin the complex plane that minimizes |f(z)|. If f and h are each analytic functions inside and on a domain C with bounding curve ∂C, and |h(z)|which will allow us to state the Fundamental Theorem of Algebra. ProblemFinish the proof of the Fundamental Theorem of Algebra, by showing that every nonconstant polynomial has a complex root. x and if the constant. (Hint: By making the right substitution, first show that we can assume the point zfrom Theoremis just the If f(x) = xn +an−1xn− +. This is the fundamental theorem of algebra: A polynomial of degree nhas exactly ncomplex roots (repeated roots are counted with multiplicity) The fundamental theorem of algebra, also called d'Alembert's theorem or the d'Alembert–Gauss theorem, states that every non-constant single-variable polynomial with complex coefficients has at least one complex root TheoremFor every polynomial f, there is a point zin the complex plane that minimizes |f(z)|. ·. So the answer to the first question is “yes.” But the answer to the second question, mysteriously, is “no:” Abel’s Theorem: There is no formula that will always produce the complex roots of a polynomial of degree 5 Fundamental theorem of algebra One of the reasons for using complex numbers is because allowing complex roots means every polynomial has exactly the expected number of roots. The test will The Fundamental Theorem of Algebra: All polynomials in C[x] (other than the constants) have complex roots.
