Equations and Their Zeros
These materials, when encountered before Algebra 1, Unit 7, Lesson 4 support success in that lesson.
In this lesson, students evaluate quadratic functions at their zeros and match other quadratic functions in standard form with equivalent functions in factored form. In the associated Algebra 1 lesson, students explore the zero product property. The work of this lesson familiarizes students with quadratic functions in factored form and begins the work to examine zeros. Students look for and express regularity in repeated reasoning (MP8) when they recognize zeros for a function in factored form.
- Practice evaluating equations
- Recognize equivalent expressions written in factored, and standard forms
- Recognize that there are 2 solutions to make an equation equal to 0
- Let’s work with equations in standard and factored forms
