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
- Enter the coefficients a, b, and c from your standard form equation (ax² + bx + c)
- Click "Calculate Vertex Form" to see the results
- The calculator will show you the vertex form, vertex coordinates, and axis of symmetry
