including weighty topics such as factoring. The vertex form of a quadratic equation is y = a(x – h)^2 + k, where "x" and "y" are variables and "a," "h" and k are numbers. In this form, the vertex is denoted by (h, k). The vertex of a ...
subtract 18 from both sides, producing y = 2(x + 2)^2 – 18. The equation is now in vertex form. In y = 2(x + 2)^2 – 18, h = -2 and k = -18, so the vertex is (-2, -18).
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. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form. y = ...

Axis of Symmetry The axis of symmetry is a vertical line that passes through the vertex You could think of it as the “mirror” that makes both sides of the parabola mirror images The axis of symmetry goes through the center of the parabola The axis of symmetry is x=h...
Finally, convert the terms inside parentheses to a squared unit of the form (x – h)^2. The value of h is equal to half the coefficient of the x term. For example, 2(x^2 – 14x + 49) – 88 becomes 2(x – 7)^2 – 88. The quadratic equation is now in vertex form. Graphi...
1. What is the vertex form of a quadratic equation? The vertex form of a quadratic equation is y = a(x-h)^2 + k, where (h,k) is the coordinates of the vertex and a is the coefficient of the squared term. 2. How do I find the vertex of a quadratic equation in vertex form?
How to Convert Quadratic Equations from General to Vertex Form Vocabulary Standard form of a quadratic equation: A quadratic equation in the form of ax2+bx+c=0 , where a, b, and c are real numbers and a≠0. Vertex form of a quadratic equation: A quadratic equation in the form...
