To get the equation into vertex form we factor the largest constant from the terms with a degree of greater than or equal to 1. H is -6 the first coordinate in the vertex. Just as a quadratic equation can map a parabola the parabolas points can help write a corresponding quadratic equation.

Let us consider a quadratic equation in Vertex Form.

The vertex of a parabola is the point at the top or bottom of the parabola. We then complete the square by following these steps finding half of the coefficients of the term. Write the vertex form of a quadratic equation. Vertex form of a quadratic equation is ya x-h 2 k where hk is the vertex of the parabola.
