Setting Up the Quadratic Formula
When using the quadratic formula to solve an equation in standard form, identify the values of a, b, and c. Enter them into the boxes and step through each line by pressing the right arrow key. Each line which appears should be on your paper as work.
Things to think about:
When the discriminant is a perfect square, what does that tell you about the number of solutions?
When the discriminant is a negative value, what does that tell you about the number of solutions?
When the discriminant is 0, what does that tell you about the number of solutions?
The purpose of the construction is for a student to check their own work. It should not be used to do the assignment.
