How to Find the Vertex of a Quadratic Equation
1 Identify the values of a, b, and c . For this article, the equation x² + 9x + 18 will be used. In this case, a=1, b=9, and c=18. Identify the values of a, b, and c. 2 First off, find the vertex's x-value . This is also the graph's " Axis ... Read More »

What is the vertex form of a quadratic equation?
The formula for the vertex form is: f(x) = a(x-h)^2 + k Where (h,k) is the vertex. The equation also tells us the direction of opening, which is the a value, in this case opens up because a is positive. It tells us the step pattern, which w... Read More »

What the Vertex form of a quadratic equations?
The vertex form of a quatdratic equation (otherwise called the graphing form) is y=a(x-h) 2 +k For those of you who don't know what 'h', 'a', and 'k' are, they are parameters. The negative sign in front of the 'h' refers to the opposite of ... Read More »

Just as a quadratic equation can map a parabola, the parabola's points can help write a corresponding quadratic equation. Parabolas have two equation forms -- standard and vertex. In the vertex form, y = a(x - h)^2 + k, the variables "h" an...

The vertex form of a parabola is y-b = c(x-a)^2 where the vertex is at (a,b) {actually the b is on the same side as x, but this is much more consistant with other geometric formulas} This formula screams out to complete the square. x^2 + 8x...

A quadratic equation is a parabolic equation and can have two general forms. The vertex form, where y equals a * (x - h)^2 + k, is named so because the vertex is given as the variables h and k. The standard form, where y equals a * x^2 + b ...
