Unit 6, Lesson 14
The Quadratic Formula and Complex Solutions
Integrated Math 2
Preparation
Lesson Narrative
In this lesson, students use the quadratic formula to calculate real and non-real solutions.
Students construct viable arguments and critique the reasoning of others when they compare solutions of equivalent quadratic equations and resolve any disagreements during a row game (MP3).
- Calculate complex solutions using the quadratic formula and represent them in the form $c \pm di$, where $c$ and $d$ are real numbers.
- Explain reasoning and critique the reasoning of others when solving quadratic equations.
- Explain when solutions are non-real when using the quadratic formula.
