Компьютерная поддержка решения школьных алгебраических задач средствами GeoGebra

This paper is presents and illustrats with examples of features of interactive environments GeoGebra to decision support of the equations and inequalities. It is shown that the use of GeoGebra to solve this kind of problems is based on the construction of geometric interpretations. Three methods of using these interpretations is considered such as: functional graphics, geometric and locus of points. The advantages and disadvantages of computer decision of algebraic problems is revealed. The content of the article will be useful for developers of software products, because it reveals the user requirements, indicates the direction of adjustment programs. Material presented in this article will be useful to specialists in the field of mathematics education, because it reveals new directions and methods of use of interactive environments in the training process.
