Teach Your Kids Algebra: The Quadratic Formula
When I first saw the quadratic formula, I was amazed that there existed such a thing no less a way to derive this elegant formula. For those who remember, this formula gives a sure-fire way of getting the solution to those things we call quadratic, or second-degree equations, in mathematics. For many students, this formula is a nightmare of grand proportions and its mastery seems no more probable than striking it rich with the lottery. However, with some novel techniques and some different a Read More...
Algebra For Dopes - It Aint That Hard - Absolute Value Part II
As we discussed in Part I of this series on absolute value, this topic is an absolute killer in algebra because of the choice that this concept presents. Absolute value can mean more than one thing, and as such, this duality of nature, so to speak, can wreak havoc on the less than intrepid warriors of algebra. However, if we break this concept down for what it really is, absolute value should never be a problem at all. You can then worry about the thousand and one other things in mathematics Read More...
Algebra for Dopes - It Aint That Hard - Absolute Value Part IV
The last of this series deals with those absolute value inequalities which are greater than some other value. These inequalities fall under the disjunctive case because the graph of these produces two distinct regions on the number line. In other words, the regions are separated by the area in between, and because of this separation we give these inequalities the name �disjunctive,� or separate. As you will see after reading this piece, these inequalities are quite simple to solve. Let�s tak Read More...
