A Least Squares Approximate Solution To Polynomial Equations Over the Real Numbers

Poole, George

Mathematics Teacher, 70, 4, 326-330, Apr 77

A geometric approach to the solution of quadratic equations and more general polynomials is based on finding points with minimum distance from the x-axis. The approach is useful in motivating the definition of complex numbers. (SD)
