About this app
For factoring quadratics this app uses the AC method. For this, only three variables must be entered. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Content ] - the variables for a, b and c must be entered - transformation of a quadratic trinomial into a product of binomials - history function to save input - detailed solution - positive and negative numbers, decimals are supported - no ads! [ Usage ] - there are 3 fields for entering the values using a modified keyboard - if values are missing, the text fields are highlighted - you can switch between the solution, input view and history by swiping and / or touching the buttons - the entries in the history can be deleted or sorted manually - if you select an entry in the history, it will be loaded automatically for the calculation - the entire history can be deleted by pressing a button
