This is an application to solve linear equations 2x2 and quadratic by different methods and step by step.Six methods are available for linear 2x2 equations: substitution, equalization, elimination, graph, Cramers Rule or by determinants and Gauss-Jordan.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.
