Locating the Vertex
In the previous lectures, we talked about methods for finding the vertex that relied on additional parabola-centric information like the location of the focus or the directrix. In this lecture, we're going to find a much more straightforwrd formula for locating the vertex based just on the three parameters, a, b and c, in the graph's equation.

In an earlier lecture, we talked about finding the vertex of a parabola based on its analytic geometry definition. In this lecture, we're going to derive a simple formula for finding its location using a strictly algebraic approach. (lecture slides)
