How do you convert a quadratic equation to Intercept Form?

Back

To convert to Intercept Form, factor the quadratic equation to find its x-intercepts.

Front

What is the Vertex Form of a quadratic equation?

Back

The Vertex Form of a quadratic equation is written as y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
