The term -b/2a has a clear graphical interpretation, and it corresponds to the position of the symmetry axis that is defined by the graph of the quadratic formula. So then, simply, the term -b/2a is the "center" of the parabola defined by a quadratic equation.

Mar 18, 2018 · 4. The Graph of the Quadratic Function. In general, the graph of a quadratic equation `y = ax^2+ bx + c` is a parabola. [You can also see a more detailed description of parabolas in the Plane Analytic Geometry section.] Shape of the parabola. If `a > 0`, then the parabola has a minimum point and it opens upwards (U-shaped) eg. `y = x^2+ 2x − 3`

Do you remember that the solution(s) of a quadratic equation is/are located where the graph intersects the x-axis. These points are also known as zeroes , roots , solutions , and x-intercepts . The discriminant provides critical information regarding the number of the solutions of any quadratic equation prior to solving to find the solutions.
