In this lesson, you will learn how to complete the square on a parabola in the form ax^2 + bx + c to find the vertex point. By using the formula, x = -b/2a, you can easily find the axis of symmetry, which is necessary for finding the vertex. This method is demonstrated on a problem of graphing the parabola y = x^2 - 4x + 5, and the steps are shown in a clear and concise way.
Graphing Parabolas; Video on How to complete the square on a parabola in the form ax^2 + bx + c to get a formula for the equation of the line that is axis of symmetry (x = -b/2a), and how to find the vertex point. The formula is used to find the vertex point for y = x^2 - 4x + 5;
