Main benefits: • Save time on your math homework • Learn about quadratics in just a fraction of time • Share solutions with your classmates. Free version offers: • Quadratic equation solver (roots, discriminant, factorization) • Formulas and guide for manually solving quadratic equations • Quadratic inequation solver Quadratic function solver (Vertex form) 3D rotating model of parabola for better understanding of quadratics in geometry Full version provides: • Detailed solution for quadratic equations • Quadratic function solver - general and factored form • Explanations and formulas for all quadratic function properties • Quadratic inequation solver with ≥ and ≤ inequality • Graph mixer - the perfect tool to play with and explore quadratic function graphs Rapid-fast solving with Single-digit input mode The full version is available for a small one-time fee. - - - - - I’ve built Quadratic Master back in 2009 when I was in high school and I was learning about quadratic equations in my math class. It is the first app I’ve ever built, and at the risk of sounding cheesy - it still holds a special place in my heart. Even though it was never a significant moneymaker, I’ve kept it updated throughout the years. And I’m happy to say that it has attained over 95.000 downloads to date. If you enjoy using the app, please consider buying the full version. Thank you. - Lukas Petr, author of Quadratic Master
