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;
 How do you find the vertex of a parabola in the form y = ax^2 + bx + c?
 What is the formula for finding the vertex of a parabola in the form y = ax^2 + bx + c?
 How do you derive the formula for the vertex of a parabola by completing the square?
 How can you complete the square to find the vertex of the parabola y = x^2  4x + 5?
 How do you convert a quadratic equation from standard form into vertex form?
This lesson explains where the formula for finding the vertex of a parabola in standard form comes from. All steps for completing the square and converting the equation from y = ax^2 + bx + c to y = a(x  h)^2 + k are explained. One practice problem is also shown.
