3 Variable Systems: Turn It Into a 2 Variable System
In this video, you’ll learn how to solve systems of equations with three variables using a simple organizational trick. Three variable systems can look intimidating but once the system becomes a standard two-variable system, the solution becomes much easier to find. In this lesson you’ll learn: • How to organize a 3 variable system • […]
Function Composition: Feed the Machines!
Function composition becomes much easier when you think of functions as machines. In this video, you’ll learn how to solve function composition problems by “feeding” the output of one function into another function machine. Instead of memorizing formulas, you’ll learn a simple visual process that helps you understand what function composition is actually doing. In […]
Wait… Why Does 0! Equal 1?
Why does 0! equal 1 instead of 0? At first glance, it seems like 0! should be 0, but factorials are about more than just multiplication. In this video, I explain the meaning of a factorial and show why there is exactly one way to arrange zero objects, which leads to the surprising result that […]
Factoring Trinomials When the Leading Coefficient is not 1
In this video, I show you how to factor trinomials when the leading coefficient isn’t 1 using the Bodine Method. Many students get stuck when the coefficient of x 2 is greater than 1, but this approach breaks the process into simple, logical steps that are easy to follow. You’ll learn: How to identify the […]
