Algebra 2- Basic Free Version | The Full Version Can Be Found Here
This course is designed as a high school second or third year college prep math course. A strong foundation in concepts and skills of Algebra 1 is required.
The first part of the course is an extensive series of sections on basic algebra topics that students should have mastered in Algebra 1. Part 2 of the course focuses on quadratic equations/complex numbers, linear systems and matrices/determinants.
The next part of the course covers functions and relations and powers and radicals at a more advance level.
The course finishes by introducing many advance level topics to include exponential/logarithmic functions and solving polynomials of n-degree. Also a chapter on rational functions is explored to include a section on graphing rational functions.

Chapter 3: Systems
Understanding systems and the methods to solve them are vital in Algebra. This chapter introduces/reviews techniques to solve linear systems. Students will also explore special systems, word problems and systems of linear inequalities. Lastly, the topic of Linear Programming will be introduced. This powerful technique uses systems to “optimize” a constraint function. Because Linear Programming is widely used in business and industry this part of the chapter is a nice way to connect concepts of systems to “real world” applications.
• 3.5 Special Linear Systems
• 3.7 Linear Programming
Chapter 4: Matrices and Determinants
This chapter introduces the core concepts of matrices and determinants to students. Time is taken to teach terminology and common applications of matrices. Students will learn how to perform various matrix operations to include matrix addition, subtraction, multiplication and scalar multiplication. Additionally, students will learn the steps to find determinants and inverse of a matrix. The chapter also focuses on how matrices can be used to solve linear systems by using an inverse matrix or Cramer’s Rule.
• 4.1 Introduction to Matrices
• 4.2 Matrix Operations
• 4.3 Matrix Multiplication
• 4.4 Determinants
Chapter 5: Quadratic Equations and Complex Numbers
Understanding the properties and methods to solve quadratic equations is essential for the student to advance in algebra. This chapter explains each concept in a very specific and focused manner. After students have been introduced to quadratic equations they build up their knowledge by learning various techniques to solve them. Additionally, they will learn the connection between solutions and graphs of quadratic functions. Methods and procedures are applied to graph quadratic inequalities and solve word problems. Lastly, the chapter covers complex and imaginary numbers. Students are introduced to complex number operations, graphs and the role complex and imaginary numbers have as solutions to equations.
• 5.4 The Quadratic Formula
• 5.7 Completing the Square
Chapter 6: Functions and Relations
Functions and relations transcend all through mathematics. This chapter explains core concepts at the Algebra 1/2 level and prepares the student for more advance study of the topic. Time is taken to explain the difference between a function and relation and introduce the student to the language of functions to include the domain, range and linear/nonlinear functions. Students will also learn function operations, composite functions and graphing.
• 6.2 Function Operations
• 6.3 Inverse Functions
• 6.4 Graphing Functions
• 6.6 Special Functions
• 6.7 Composite Functions
Chapter 7: Powers and Radicals
This chapter covers all the rules a student will need to know to work with powers, exponents, radicals and rational exponents. Also, important applications of these rules are coved to include scientific notation, compound interest, Pythagorean Theorem and the Distance and Mid-Point formula. Special emphasis is placed on solving radical and rational root equations.
• 7.4 Scientific Notation
• 7.5 Compound Interest
• 7.6 Simplifying Radicals
• 7.7 Operations with Radicals
• 7.11 The Pythagorean Theorem
Chapter 8: Logarithmic and Exponential Functions
For most students this chapter will be their first introduction to logarithms. As such the chapter focuses on teaching the basic core concepts of a logarithm and its relationship to an exponential function. Students will learn how to covert between a logarithm/exponential equation.
Additionally, the chapter defines the properties of logarithms and how to condense and expand logarithmic expressions. The Natural Base e and Natural logarithms are explored with explanations of how to use the “log and ln” functions on a scientific calculator. Finally, the chapter covers the methods and procedure to solve exponential and logarithmic equations.
• 8.3 Properties of Logarithms
• 8.4 The Natural Base e
• 8.5 Natural Logarithms
Chapter 9: Polynomial Functions
The first part of the chapter covers the parts of a polynomial, related terminology and how to perform polynomial operations. A special focus is placed on the extremely important skill of factoring polynomials. Students will understand how to factor out a polynomial GCF and build on this to learn many techniques to factor polynomials.
Lastly, the chapter goes into the various methods and techniques to solve a polynomial of any degree. Students will specifically learn how to apply key concepts, skills (polynomial long and synthetic division) and theorems (Rational Root and Fundamental Theorem of Algebra) to find the roots of polynomial functions.
• 9.3 Multiplying Polynomials
• 9.8 Special Factoring Rules
• 9.9 Graphing Polynomials
• 9.12 Remainder and Factor Theorem
Chapter 10: Rational Expressions/Equations
The first part of the chapter takes the student through fundamental rational expressions to include ratios, rates, proportions, percent and variation. Special emphasis is placed on learning different methods to solve rational expression problems. The section on simplifying rational algebraic expressions starts by reviewing basic examples using numbers before introducing variable examples.
The second part of the chapter builds from the student’s knowledge of polynomials and covers operations with rational expressions. Instruction will focus on learning to multiply, divide, find the LCD and solve rational expressions. Additionally, a section is dedicated to the procedure/ methods to graph rational functions; new terms like vertical and horizontal asymptotes will be explained.
