"  A Simple Proof of the Fundamental Theorem of Algebra (FTA) "
  Aaron Bailey  


In this talk, a truly elementary proof of FTA will be shown in detail. The scheme of the proof is (with modification) due to Jean-Robert Argand in 1815. The argument is characterized by its simplicity, and avoids the usual complex analytic, topological, or algebraic machinery which is usually used. At its deepest, only introductory “advanced calculus” level analysis and complex arithmetic is required.
