Hi, welcome to the DeltaSolve testing family

This is an excellent and well-designed app. I've tried several calculators for solving quadratic equations, but this one stands out for its accuracy, clarity, and ease of use. The interface is clean and intuitive, and the results are presented in a clear and understandable way. It's evident that a lot of thought and care went into the development of this app. I highly recommend it to students, teachers, or anyone who needs a reliable tool for solving root formulas.
