Unit 6: Quadratic Equations

In this unit, students use algebra to solve quadratic equations in one variable. This includes factoring quadratic expressions as well as using the quadratic formula and completing the square to solve quadratic equations. Students should make connections between different methods of solving a quadratic equation to inform their solution pathway. Students will also build on their earlier work with linear systems by using algebra and graphing to solve systems consisting of a linear equation and a quadratic equation in two variables.
