Vertex Form Calculator

Convert quadratic equations from standard form (ax² + bx + c) to vertex form: a(x - h)² + k

Understanding Vertex Form

The vertex form of a quadratic equation provides key information about the parabola:

  • h represents the x-coordinate of the vertex
  • k represents the y-coordinate of the vertex
  • a determines whether the parabola opens up (a > 0) or down (a < 0)

How to Use This Calculator
