Find zeroes and factors of polynomials
In this example we use the rational root theorem and synthetic substitution to find the zeros and factors of a polynomial to the third degree.

Verifying Trigonometric Identities 2
In this episode, there are 2 examples of verifying trig identities that I would rate on the more difficult side. More advanced strategies are needed such as factoring and finding a common denominator. While that sounds easy, it is often difficult to see when verifying trig identities.

Verifying Trigonometric Identities
In this episode, we look at verifying trig identities. There are 3 examples that I would rate on the easier side. You need to start somewhere.

What is a Podcast?
This podcast is not about math. This is just a simple explanation of what a podcast is. I have created this podcast to help my students learn more about podcasts. They will eventually help me make more math podcasts. I am very much so looking forward to this project.

Solve a quadratic equation by using substitution 2
Here is another example how to use substitution to solve a quadratic equation. Now I know that there are other ways to solve this particular example (squaring both sides), but I wanted to show that substitution is a good way to solve a quadratic equation.

Solve a quadratic equation by using substitution
Sometimes we will encounter a problem that just looks ugly. In other words, it is one of those problems we just would rather skip. However, as you will see in this problem, substituting a quantity for a single variable really does make the problem much more manageable.

Graphing a quadratic in vertex form 2
Here is another example of graphing a quadratic equation that is in vertex form. In this example, a is negative which causes the graph to open down and frown:-(
-
Graphing a quadratic in vertex form
Graphing a quadratic equation is not a difficult task. Here are the main things to find: the vertex, the axis of symmetry, the y-intercept, and the x-intercepts. Use the fact that a parabola is symmetrical also makes it easier for us to find additional points.

The quadratic formula.
Here is a bit of fun I had with one of my Alg II classes reviewing the quadratic formula.
-
Using the quadratic formula to solve a quadratic equation 2.
Here is another example of solving a quadratic equation using the quadratic formula.

Using the quadratic formula to solve a quadratic equation.
A great way to solve a quadratic equation is by using the quadratic formula. It is straight forward and user friendly in my opinion. Many students prefer using the quadratic formula over the other leading brands of solving a quadratic equation.

Special Edition Completing the Square
In this next example, you will see just how great completing the square really is. At the end, you might recognize the solution.

Solve a quadratic equation by completing the square 3
Some students do not like to use the process known as completing the square. However, I will show you just how easy it really is to complete the square.

Solving an equation containing two radicals
In our next example, we are going to solve an equation that contains two radicals. No matter what we do, we must always try to isolate the radical before we start to solve the equation. It does not make a difference which radical you isolate, but isolate one of them. Once the radical is isolated,...

Solving an equation containing a radical
In like our next like example, like we are like going to like solve a radical equation. Oh, sorry about that. Let's try that again. In our next example, we are going to solve an equation that contains a radical. No matter what we do, we must always try to isolate the radical before we start to...

Simplifying a complex fraction
Some think that fractions are complex enough. But when there is a fraction within a fraction, it really gets complex. To make the problem easier, multiply both the numberator and denominator by the least common multiple to get rid of the fractions within the fractions. You might need to factor…

Solving an equation with variables in the denominator #2
In this example, we solve an equation with fractions but with varibles in the denominator. If you do not like to work with fractions, find the least common multiple of the denominator. Then multiply each term by the least common multiple and voila the fractions are gone and you can solve the...
