Quadratic Formula Calculator

Solve quadratic equations using the quadratic formula. Calculate roots, discriminant, vertex, and determine root types (real or complex) with step-by-step explanations and history tracking.

Key Features

  • • Solve quadratic equations (ax² + bx + c = 0)
  • • Calculate discriminant (Δ = b² − 4ac)
  • • Identify root types (real, repeated, complex)
  • • Compute roots using quadratic formula
  • • Vertex calculation (parabola turning point)
  • • Step-by-step solution breakdown
  • • Handles real and complex number solutions
  • • Input validation and error handling
  • • History tracking using local storage
  • • Export results with calculation steps

Use Cases

  • • Algebra and mathematics problem solving
