Video Learning Notes
In this lesson, students learn to solve quadratic equations with real solutions using factoring, taking square roots, completing the square, and the quadratic formula. They also use technology to write quadratic functions that fit real-world data, enabling them to estimate solutions and make predictions. Emphasis is placed on evaluating the reasonableness of solutions and connecting mathematical methods to practical situations, preparing students for further study and application of quadratic functions.
Learning Goals
- Solve quadratic equations with real solutions by factoring, taking square roots, completing the square, and using the quadratic formula.
- Use technology to write quadratic functions that fit data reasonably well to estimate solutions and make predictions for real-world problems.
