I use relays to review a lot of different subjects in my Algebra 2 classes. This one reviews Sections 5.4 through 5.8 of the Prentice Hall CA Algebra 2 textbook. It has 20 quadratic equations for students to solve. Some can be factored, but many have irrational or complex solutions.
NOTE: This could not be used for Algebra 1 because of the complex solutions. I have one that is appropriate for an Algebra 1 class at: Algebra 1 Solving Quadratic Equations
Students have fun with Scavenger Hunts. They try hard to find the correct answer so their team can finish first!
It includes instructions of how to use the Scavenger Hunt, a worksheet that students can use to record their answers, and a homework worksheet that asks students to solve 24 quadratic equations: 6 by taking square roots, 6 by factoring, 6 by completing the square, and 6 by using the quadratic formula.

Common Core Standards:
A-REI 4. Solve quadratic equations in one variable.
A-REI 4b. Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula, and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
N-CN 7. Solve quadratic equations with real coefficients that have complex solutions.
Previous California Standard for Algebra 2:
8.0 Students solve and graph quadratic equations by factoring, completing the square, or using the quadratic formula. Students apply these techniques in solving word problems. They also solve quadratic equations in the complex number system..
