Today we reviewed how to use the discriminant for quadratic equations.
Here are the marked slides from class.
Here is a list of the topics that will be on the Exam that is on Thursday (10/11/12) of this week.
Your homework for tomorrow is page 73, #21-25. This might be on the HW Quiz.
You have a HW Quiz as part of your homework grade tomorrow, Wednesday 10/10/12. Don't forget to bring your homework assignments to class. I will give you 10 problems taken straight from the homework: in the time I give to you (not the full period) you should just copy the problem from your homework onto the sheet. The HW Quiz will only be problems assigned from the textbook.
This is my way of checking for accuracy on homework assignments, as I have only been checking for completion up until now. I will continue to use this system throughout this year, where each unit/chapter will culminate in a HW Quiz.
There's been a lot of good problems in the homework. I think #3 on page 45 is a good problem. Also, #20 on page 52 is a good thought provoker. Page 64 also had some interesting problems, like question #7 for example. Question #2 on page 73 was a nice one to practice completing the square. Those sure were some good problems.
