Algebra 2H pd 1
After reviewing the quadratic formula hw, we learned about b^2 - 4ac being called the discriminant. This number tells you how many real solutions are in the quadratic equation. It does NOT tell you what those solutions are. We also started the unit on complex and imaginary numbers. We learned the i=sq root of -1.

Algebra 2A pd 5
We reviewed the quadratic formula and then learned how the discriminant (b^2-4ac) is used to tell you how many real solutions are in the quadratic equation problems.
HW Do the second side of the worksheet we started in class today.
