### Intermediate Algebra - Solving Non-Linear Systems of Equations (Part A)

In this video, we introduce the idea of solving non-linear systems of equations involving quadratic equations and linear equations. A future lecture will be done covering how to solve other types of non-linear systems.

### Intermediate Algebra - Quadratic Inequalities (Part A)

In this video, we reintroduce the idea of inequalities prior to jumping into solving quadratic inequalities.

• 37:46

### Intermediate Algebra - Graphing Systems of Linear Inequalities

In this video, we reintroduce the idea of inequalities, but this time involving two variables. We then graduate into systems of linear inequalities. Finally, we see how to graph the solution set to a real-world system of inequalities.

### Intermediate Algebra - Review 1: Number Systems

In this video we explore the number systems (sans the complex numbers) and discuss, in some detail, how to determine whether a given number belongs to a certain number system. Finally, we delve into the axioms that make our system of mathematics work so w

### Intermediate Algebra - Logarithms: Applications Requiring Logarithms

In this video, I cover some very cool applications involving the need for logarithms. I also discuss continuous compounding briefly at the end.

### Intermediate Algebra - Exponential Functions: Creating from Applications

In this video, I show you how to identify situations that call for exponential functions as well as how to create the exponential functions for these applications.

• ### Intermediate Algebra - A Brief Review of Multiplying and Factoring Polynomials (Part C)

In this video, I do an extremely truncated review of factoring methods. I also introduce a better way to approach the "diamond/box/ac-" methods.

### Intermediate Algebra - Slope (Part A)

In this video, we discuss the ideas of comparison of ratios and steepness.

• 52:29

### Intermediate Algebra - Logarithms: Solving Any Exponential Equation

In this video, I show how to use the properties of logarithms to solve any exponential equation (that can be solved algebraically). I also discuss natural logarithms briefly.
