Move the constant on the left-hand side of the equation back over to the right by adding or subtracting it. In the example, 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 = -1...

Fireworks – Vertex Form of a Quadratic Equation • Vertex form y = a·(x – h)2 + k allows us to find vertex of the parabola without graphing or creating a x-y table. y = (x – 2)2 + 5 a = 1 vertex at (2, 5) y = 4(x – 6)2 – 3 a = 4 vertex at (6, –...
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. Graphing ...
