A real number x will be called asolution or a root if it satisfies theequation, meaning . It is easy to see that the roots are exactly the x-intercepts of the quadratic function , that is the intersection between the graph of the quadratic function with the x-axis. a<0. a>0. Example 1: Find the roots of the equation.
With the above parameterization, the quadratic formula is: Each of the solutions given by the quadratic formula is called a root of the quadratic equation. Geometrically, these roots represent the x values at which any parabola, explicitly given as y = ax2 + bx + c, crosses the x-axis.
