Marco figural como medio para factorizar polinomios cuadráticos

This article is a proposal for the teaching and learning of factoring quadratic polynomials, based Regine Douady´s theoretical frameworks regarding the Tool-Object Dialectic. It highlights the role of combined mathematical frameworks as a means to access... "different formulations of a problem which, without necessarily being equivalent, allow a new approach to the difficulties encountered and the staging of tools and techniques that were not imposed in the first formulation." From this perspective, an axiomatic system is constructed in a figural context in which primary objects are defined, ...
