This worksheet is designed as a group activity for groups of 3. Each member of the group will get a worksheet in which he/she needs to solve by factoring, using the quadratic formula or completing the square.
The group members will compare their answers with each other which helps visualize that no matter which method you use, the answer will be the same. If there is a disagreement in the answers students must work together to problem solve and find the error. It is great practice for error analysis.
Answer key is included.
