In this lesson, students discuss methods for checking their solutions to a solved equation and focus on the order of the steps to solving a quadratic equation using the quadratic formula. In the associated Algebra 1 lesson, students examine common errors and verify solutions to quadratic equations. The work of this lesson supports students by focusing on a few methods for checking solutions and the order of steps needed to use the quadratic formula. Students have the opportunity to construct viable arguments (MP3) when they explain what steps should be taken to solve and check the solution for a quadratic equation.
- Determine the order of steps to solve a quadratic equation using the quadratic formula.
- Verify solutions to equations.
- Let’s work to solve quadratic equations.
