Convert y 2x2 - 4x 5 into vertex form and state the vertex. Completing the Square To convert a quadratic from y ax2 bx c form to vertex form y a x - h 2 k you use the process of completing the square. Just as a quadratic equation can map a parabola the parabolas points can help write a corresponding quadratic equation.
Convert y 2x2 - 4x 5 into vertex form and state the vertex.
Vertex form of a quadratic equation is ya x-h 2 k where hk is the vertex of the parabola. The vertex of a parabola is the point at the top or bottom of the parabola. 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. Vertex form of a quadratic equation is ya x-h 2 k where hk is the vertex of the parabola.
