we have the original equation (or, if we had to solve first for "= 0", the "equals zero" form of the equation). In this case, we were asked for thex-intercepts of a quadratic function, which meant that we set the function equal to zero. So we're good to go. Our starting poin...
Particularly for the discriminant it is important to know because it allows to study the graph of the equation. The roots are equal to the x – axes cut of the graph of the function which is parabolic. The discriminant makes it possible to analyze how this parabola is positioned with respec...
