The roots of the quadratic equation ax2 + bx + c = 0, where a, b, & c are real numbers, and a ? 0, are given by the following formula: In this formula the term b2-4ac is called the discriminant. If b2 - 4ac = 0, so the equation has a single repeated root. If b2 - 4ac > 0, the equation has two real roots. If b2-4ac < 0, the equation has two ...

The coefficient c controls the height of the parabola; more specifically, it is the height of the parabola where it intercepts the y-axis. Vertex. The vertex of a parabola is the place where it turns; hence, it is also called the turning point. If the quadratic function is in vertex form, the vertex is (h, k). Using the method of completing the ...
