Quadratic Solver

Type in a quadratic equation, hit solve, and Quadratic Solver breaks down every step — factoring, applying the quadratic formula, simplifying the discriminant — so you can see exactly how the answer was reached, not just what it is. It's built for students checking homework, teachers demonstrating technique, or anyone who's stared at ax² + bx + c = 0 and needed a clear walkthrough rather than a bare number.

The step-by-step output is what separates this from punching values into a basic calculator. Each stage is labeled, so if you get lost partway through a problem, you can pinpoint exactly where your own working went wrong. If broader number-crunching is what you need, Statistics Calculator covers similar ground for descriptive stats and data sets. Both live in the tools category alongside other handy utilities.

Works entirely in the browser with no sign-in required — keyboard entry is the fastest way to get results, so it shines most on desktop where you can type coefficients quickly and scroll through the full solution without zooming in.
