This is an application to solve linear equations 2x2, 3x3 and quadratic by different methods and step by step.

Six methods are available for linear 2x2 equations: substitution, equalization, elimination, graph, Cramer's Rule or by determinants and Gauss-Jordan.

Linear equations 3x3 contains so far a method: Cramer's rule or determinants.

For quadratic equations three methods are available: General formula, perfect square trinomial and also the generation of the graph of the equation is available.

It is also able to factor quadratic equations of the form x²+bx+c=0,a=1 and ax²+bx+c=0, a≠1.

In future updates we will be adding several methods, both in linear and quadratic equation systems.
