In this fourth lesson for Math 20-1 Quadratic Equations, we will explore another way to solve a quadratic equation. The Quadratic Formula will work for every equation and provides both exact and approximate solutions.

Lesson notes are provided that align with the videos. Students are encouraged to have a hard copy of the notes available as video instruction occurs. At any point, the lesson can be paused and questions can be self completed to check understanding.The intent is that active engagement with the material, will increase both confidence and level of understanding.

Animated google slides are included. The content in the videos and on the slides is the same. Students seeking a more individualized approach can move through the google slides without the videos. There is a conscious effort to provide flexibility with regards to learning styles.

And lastly, the lesson has a set of accompanying practice questions. After receiving instruction, it is critical to assess the level of understanding. Detailed solutions are given. Following each question, check the answer. If correct, confidence grows. If not correct, discovering the solution process on your own can prove to be a significant advantage. These questions and answers are designed to solidify learning.
