No more formal lectures. All material has been covered.
On Monday, July 1 we’ll do a sample exam 3 to review Chapters 8 and 9.
On Tuesday, July 2, we’ll do a sample Final Exam.
You may take Exam 3 and the Final the week in class for your 10 big bonus points.
Last day of the class is Friday, July 5. No class on Thursday, July 4.
To give you an accurate reflection of what your grade is as of now, all work that should be completed, but isn’t, has been issued a zero. Your grade average in mymathlab will reflect that. Now of course if you do those homeworks and quizzes, whatever grade you get will overwrite the zero. So get that work done!
Remember when the course is scheduled to be officially done, July 5 @ 12:30pm, then that’s it. The course shuts down, I submit the grades, and we get a divorce. It’s over!
SetJavaPathV5.vbs — This utility will set the Environment PATH variable to include the directory where the JDK is located. This utility is handy when running the JDK tools from the command line. Just download it, unzip the vbs file, and click it. It will probably take awhile for the program to find the JDK, so be patient!
All course announcements and correspondence will be done through this page. It is your responsibility to visit this course page at least once every two days to view the latest course announcements, homework, and news. It is unacceptable to say that you are not aware of something happening in the course.
Students can call the Student Success Center to make an appointment with a tutor at (413) 755-4715. They can also stop in to make an appointment. We are located in B19, second floor, next to the Library.

If your expression was a number other than 1 in front of the squared term, I call that number “magic” because it is involved in a few magical steps to get an answer.
Suppose you’d like to factor this expression:
Step 1: Factor out the GCF if possible. In this example, there is no GCF. You must factor out a GCF before you continue to step 2.
Step 2: Convert the expression to one where the squared term has a coefficient of 1. Do that by stripping the squared term of its current coefficient, in this case 15 and call that number the “magic number“.
Create another expression that has a squared term, the same middle x term, and the last constant being the magic number multiplied by the original constant. Here is the new expression to deal with:
Step 3: Factor the new “simplified” expression to get
Step 4: Using the “magic number”, which in this case is 15, make fractions out of the numbers generated in step 3. Here is the expression:
Step 5: Simplify the fractions. This is the result of the simplification:
Step 6: If you still have fractions after simplifying the fractions, move the denominations of those fractions to the front of the variable. Here’s what we get:
I have some ideas for apps to add to this website, so please visit every now and then.
If you have an idea for an app that you think would be useful, would benefit a student, or would make the world a better place, please share ( firstname.lastname@example.org ), and if it isn’t too involved, and I have the time, I’ll code the problem and make it a special app.
There are math lecture videos based on our textbook. You can access them here: Algebra Videos (This is STCC’s portal website. You’ll need to login with your Webadvisor credentials.) If you miss a class or need another prospective on the material, give these videos a try.
To take these courses, you must have access to a computer as this will be a hybrid lecture / online study course. We will be using http://www.mymathlab.com/. So you must purchase the Student Access Code package and register using the appropriate Course Code (ID) shown above.
