| The Roots of a Quadratic Gizmo is a great introduction to solving quadratics because it demonstrates that the solutions of a quadratic equation are equal to the x-intercepts of the parabola of the corresponding quadratic function. Students can use the Gizmo to:
1) Find the axis of symmetry 2) Calculate the discriminant to find the number of real roots 3) Practice using the quadratic formula to find both real and complex roots for quadratic equations Be sure to go through the derivation of the quadratic formula with your class, which is found in the Teacher Guide for this Gizmo. Now, let’s get to the root of those quadratic equations! |
