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

In this video, we discuss the part of a polynomial (terms, monomials, binomial, trinomials) as well as the degree of a polynomial.

• ### 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 - A Brief Review of Multiplying and Factoring Polynomials (Part D)

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 - Additional Properties of Lines (Part A)

In this video, we explore horizontal and vertical lines and their slopes.

• ### Intermediate Algebra - Additional Properties of Lines (Part B)

In this video, we discuss the properties of parallel and perpendicular lines.

• ### Intermediate Algebra - An Introduction to Systems of Equations (Part A)

In this video, we introduce the idea of a system of equations and how to solve a system graphically.

• ### Intermediate Algebra - An Introduction to Systems of Equations (Part B)

In this video, we discuss the ideas of consistent and independent systems, consistent and dependent systems, and inconsistent systems.

• ### Intermediate Algebra - An Introduction to Systems of Equations (Part C)

In this video, we show how useless it is to use graphing (by hand) to solve a system of equations - especially for an application.

• ### Intermediate Algebra - Building and Using Linear Models

In this video, we combine all of our knowledge to build linear models for application problems and interpret the meaning of the results.

• ### Intermediate Algebra - Completing the Square (Part A)

In this video, we introduce the idea of completing the square; however, we do not use it yet to solve quadratic equations.

• ### Intermediate Algebra - Completing the Square (Part B)

In this video, we using completing the square to solve quadratic equations.

• ### Intermediate Algebra - Equations of Lines (Part A)

In this video, we develop the slope-intercept form of a linear equation. A "proof" of this form is also given.

• ### Intermediate Algebra - Equations of Lines (Part B)

In this video, we simplify graph linear equations using the slope-intercept form of a line.

• ### Intermediate Algebra - Equations of Lines (Part C)

In this video, we explore the point-slope form of a line (although, it's more entertaining to think of it as the pointless-slope form of a line).

• ### Intermediate Algebra - Equations of Lines (Part D)

In this video, we derive equations of lines from graphs.

• ### Intermediate Algebra - Everything About Graphing Parabolas

In this video, we discuss how to graph parabolas given in standard form, using the discriminant to determine the number of x-intercepts and plotting the x-intercepts. I also do a brief introduction to the vertex form of a parabola.

• ### Intermediate Algebra - Exponential and Logarithmic Functions: Solving Equations

In this video, I cover how to solve exponential and logarithmic equations.

• ### 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 - Exponential Functions: Graphs of Exponential Functions

In this video, I cover all the concepts required to successfully graph basic exponential functions.

• ### Intermediate Algebra - Exponential Functions: Solving Exponential Equations (no logs)

In this video, I discuss how to solve exponential equations that do not require the use of logarithms. I also show how to build an exponential model using a graphing calculator.

• ### Intermediate Algebra - Exponential Functions: The Concepts

In this video, I introduce the concept of an exponential function through an exploration of exponential growth. I also talk about the base multiplier property.

• ### Intermediate Algebra - Functions: Finding an Equation for the Inverse Function

In this video, I show you (rather long-windedly) how to find the equation of the inverse function (if it exists). I also discuss the weaknesses of the current inverse function notation.
