Great Algebra 2 Course

Want to take a lecture course, but do your exams at home…then these Algebra courses are for you!

Hello!  My name is Prof. Tony Silvestri, and this is a quick note to make you aware of the Algebra course I am teaching this Summer 2019.

I have these sections scheduled:

  • MAT-097-E12 on MTWTH at 10:30am (Algebra 2)

What sets my courses apart from many of the other Algebra courses is I try to eliminate the anxiety many students have towards math.  I do this by allowing you to take the exams AT HOME where you can take your time, use your notes, and other resources!

If that isn’t enough, you get 2 takes on the exam.  The better grade of the two takes gets entered in your record!

This idea of home testing may be controversial to some who teach a traditional lecture class.  But my experience with this technique showed much more student success than what tradition offers.

Another feature that sets this course apart from the online courses is that you get to listen to me describe what’s needed to solve the algebra problems.

I also provide some special apps I wrote that you can use to help you navigate through your algebra 2 journey.  Check them out here:  Special Apps!

Here is an unsolicited comment a student emailed me about my course:

I was so bad at math during my HS times, idk why but being in your class, math makes sense and i can understand.. for example, i’m weakest at graphing and never understood, but being in your class, i’ve improve and i can feel it. Well, good luck to me. PS, you are too funny sometime.

It is nice to get comments like that!

So if you have an algebra phobia, or if you just want to increase your level math proficiency to prepare for college level math, then this is the course for you!

To take my 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/.

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.
