✨ Key Features

  • ⚡ Instant Real-Time Solving: Type or adjust coefficients $a$, $b$, and $c$ to instantly calculate roots, vertex, axis of symmetry, and discriminant.
  • 📝 Step-by-Step Working: Shows every arithmetic step, radical simplifications, and exact fractional/radical forms — designed like an in-class textbook solution.
  • 🎯 All Root Types Supported:
    • Distinct real roots ($\Delta > 0$)
    • Repeated single real root ($\Delta = 0$)
    • Complex conjugate roots ($\Delta < 0$) with clean $i$ notation
  • 📈 Interactive Parabola Grapher: Hardware-accelerated HTML5 Canvas with auto-scaling coordinate grid, vertex locator, and root markers.
  • 🌍 36 Native Languages & Full RTL Support: Fully localized across 36 languages with bidirectional layout support (Arabic, Hebrew, Persian, Urdu).
  • 🚀 100/100 Core Web Vitals: Static Site Generation (SSG) with Astro, Vite, Tailwind CSS v4, and 0KB framework runtime overhead.
