Coming up:
Grade report #3 due Monday, 10/31 (Happy Holloween!)
Group Test 5-1 on Wednesday, and the individual test 5-1 on Thurs. 11/10

And don't forget to change your clocks back 1 hour! That's 1 extra hour for catching up on your homework!

Here are the notes from Friday on factoring 2 cubes and also the Zero Product Property. I had some computer trouble and temporarily lost the file. I also found this site below for a good summary of special factors [Benchmark 4.2]
Intermediate Algebra Tutorial on Factoring Special Products

First, Practice BM 8.1
Then Benchmark 8.1
After that, 5.1 Graphing Quadratics
        Alg2_5.1_Notes.pdf
Topics:
• Parabola and axis of sym.
• standard form
• Vertex form
• intercept form
• Graphing
HW: #23 page 253 #17-51 (o), 52, 57-65 (o)
On Friday: Retake benchmarks 8.1 and 4.1-4.2

We started class with benchmarks. 4.1 and 4.2 on Factoring as well as retakes for 3.1-3.3. We went over HW #22 from Friday and collected it. Benchmark 8.1 (solving by factoring) on Wednesday.

Due to some computer issues, I will be putting the problem of the week up a little later this week. Stay tuned.

We checked and collected HW #21, and then took notes on Factoring the sum and difference of 2 cubes. Then we took notes on the zero Product property. The homework is #22 page 261 #65-79 all, 107-125 (odd). Notes won't be online for a while. Sorry.

Reminder: Benchmarks 4.1 and 4.2 on Monday.

First, we checked and collected #20, then went right into the notes (5.2 continued).
        Alg2_5.2_Notes_part2.key
We covered these topics-
• ax^2+bx+c, a≠1
• Special Factors
• ending variables
Played Me Vs. You, and here's the homework.
HW: #21 page 260 #23-63 (o)
We also checked BM #3.1-3.3 because the retakes on on Friday. Here are the solutions since 6th period didn't have time to go over it.
        Alg2_BM_3.1-3.3_Sol.pdf

We started class right away with some notes on "Intro to Quadratics and Factoring". We covered these topics:
• GCF
• ax^2+bx+c, a=1
        Here are the notes and the assignment will come later.
HW: #20 Factoring WS

Suppose you put 1 penny in your piggy bank on the first day of the month. On the second day, you put 2 pennies in, 4 pennies on the third day, etc. Each day double the previous day’s amount.
How much would you have saved after 31 days?

Today was the Chapter 3 Test. If you missed it, the deadline to make it up is Wednesday, Oct. 19. After the test, we took benchmarks 3.1-3.3 on Polynomials. (It was what we reviewed for on Wednesday).

Have a nice weekend. Check for the Problem of the Week on Sunday!

We started class with the assignment: #19 6.3C WS #1-35 (odd)
        Alg2_6.3C_WS.pdf
Then we review BM 2.4 (retake on Friday after the test) and practiced for BM 3.1-3.3 (also after the test on Friday)

Reminder: Last day for grade reports are Friday, Chapter 3 Test on Friday, and BM 3.1-3.3 Friday

First, grade reports were due today. The announcement was on the board for over a week. You do have until Friday to turn them in.
We reviewed the Chapter 3 Group Test from Wednesday. Here are the solutions. The Ch. 3 Test will be on Friday, 10/14.
Then we checked #18 and answered questions. This is a review for Benchmarks 3.1-3.3 (on Friday, too).

Snappy the snail is climbing a slippery 30-inch wall. Each minute he climbs up 5 inches and then slips back 4 inches. How long does it take Snappy to climb the wall?

Sorry, but I'm out today. There is some classwork, notes, and homework. If you get stuck, there is hotmath.com. You can post comments (or frustrations) for points! Take advantage of the opportunities!

Classwork: #17 page 192 #7-41 (o)[skip 33], 49-57 (o), 65, 66, 67, 76 Due at the end of the period!

6.3: Adding, Subtracting, and Multiplying Polynomials
Copy examples 1-6 and Special Products Box on pages 338 for your notes
HW: #17 page 341 #17-61 (odd)

Reminders: Grade report-Mon. 10th, BM 2.4 retake-Wed. 12th, Test-Fri. 14th

If you are trying to get extra points by making comments, you need to add your comments to the appropriate class date. There is a HIGH probability that if you post your comments on an older entry (like the original posting for points), you won't get credit. I check the posts on a weekly basis to give points, and if you post on something older, it won't be counted.

SparkNotes: Systems of Three Equations: Solving by Addition and Subtraction
This link has some explanation and examples of solving the dreaded 3 variable systems of equations (x, y, z). Its worth a look. There are practice problems here.

If you need some more help with 2 variable systems, check this out.

I don't feel we are ready for this test. Part of it is due to the complexity of the material, and part of it due to the lack of effort on the student side. I want to give as many opportunities for success, so rather than taking the test today, we will take a group test. This test will be identical to individual test. The individual test will be next Friday, Oct. 14th. This Friday we will go over the group test and get solutions. These will act as your study guide.
I know this is a week later, but I want everyone to have enough time to study and get questions answered. We will continue with the next chapter in class, and our warm-ups will keep some concepts fresh.
Remember, you can get extra points for posting comments. I'm providing opportunities, you need to take advantage of them.

You will only get out as much as you put in.

Here is the practice test if you were absent.

MS: 3-var system
BM #2.4 and retake 2.1-2.3
