Essential Question How do I use the quadratic formula to solve quadratic equations?

If an equation can be factored, factoring is usually the quicker method. However, not all equations can be factored easily. In this case, the quadratic equation always works!

Activity On a sheet of notebook paper, choose 10 problems from the assignment to work. Show all your work! You can work with a partner but each person needs to turn in their own paper.

Reflection Do you like using factoring or the quadratic formula to solve quadratic equations better? Why?
