visualize complex roots
In this activity, you will explore complex roots using the quadratic formula.
1. When does the blue graph have two unique solutions?
2. When does it have a single solution?
3. When does it have complex solutions?
To get started try the equation . What is the x value of its vertex and the distances from this x value? What are its roots using the TI way of thinking? Check your answer by using the quadratic formula.
