Algebra 1 – Progress as of Friday, February 15

As of Friday, February 15, we finished Chapter 2  This means you must complete all the HW for chapter 1 and 2 and Quizzes 1A, 1B, and 2A, 2B.

Exam 1 on Chapters 1 and 2 is now available and is due in a week.  You have 2 takes on the exam.

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!

See on Tuesday, Feb 19.  It follows a Monday schedule.

Algebra 2 – The “Magic Number” Technique to Factoring

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:

That’s it! That is your answer! Neat huh?

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 ( silvestri@stcc.edu ), and if it isn’t too involved, and I have the time, I’ll code the problem and make it a special app.
