In this lesson, students find solutions to quadratic equations and recognize the solutions as \(x\)-intercepts of related functions then match equivalent equations. In the associated Algebra 1 lesson, students solve equations in factored form. Practicing finding equivalent equations and their solutions, gives students additional support before working with the Algebra 1 lesson. Explaining why equations are equivalent requires students to construct viable arguments and critique the reasoning of others (MP3).
- Recognize solutions to quadratic equations as $x$-intercepts
- Let’s explore equivalent equations
