When using the quadratic formula to solve an equation in standard form, identify the values of [i]a[/i], [i]b,[/i] and[i] c[/i]. 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.[br][br]Things to think about:[br]When the discriminant is a perfect square, what does that tell you about the number of solutions?[br]When the discriminant is a negative value, what does that tell you about the number of solutions?[br]When the discriminant is 0, what does that tell you about the number of solutions?[br]

The purpose of the construction is for a student to check their own work. It should not be used to do the assignment.
