### Int Algebra: Find Vertex by Completing the Square

http://www.mindbites.com/lesson/946 for full video In this lesson, you will learn how to find the vertex of a parabola given the formula for the parabola. To do this, you will complete the square. By completing the square of the parabola equation, you will be able to get the equation into a standard form that can be more easily evaluated. A parabola is a conic section in which the locus of points constructing it are equidistant from the focus and the directrix. Once we've identified the vertex of a parabola, we can get a good sense for how the parabola is positioned on the Cartesian coordinate plane. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive Algebra course.
