Beginning Algebra
Purpose of Course showclose
In this course, you will study basic algebraic operations and concepts, as well as the structure and use of algebra. This includes solving algebraic equations, factoring algebraic expressions, working with rational expressions, and graphing linear equations. You will apply these skills to solve realworld problems (word problems). Each unit will have its own application problems, depending on the concepts you have been exposed to. This course is also intended to provide you with a strong foundation for intermediate algebra and beyond. It will begin with a review of some math concepts formed in prealgebra, such as ordering operations and simplifying simple algebraic expressions, to get your feet wet. You will then build on these concepts by learning more about functions, graphing of functions, evaluation of functions, and factorization. You will spend time on the rules of exponents and their applications in distribution of multiplication over addition/subtraction.
This course provides students the opportunity to earn actual college credit. It has been reviewed and recommended for 3 credit hours by The National College Credit Recommendation Service (NCCRS). While credit is not guaranteed at all schools, we have partnered with a number of schools who have expressed their willingness to accept transfer of credits earned through Saylor. You can read more about our NCCRS program here.

 Final Exam
In order to “pass” this course, you will need to earn a 70% or higher on the timed, twohour final exam. Your score on the exam will be tabulated as soon as you complete it. If you do not pass the exam, you may take it again.
Time Commitment: This course should take you a total of 104 hours to complete. Each unit includes a time advisory that lists the amount of time you are expected to spend on each subunit. These should help you plan your time accordingly. It may be useful to take a look at these time advisories to determine how much time you have over the next few weeks to complete each unit and then set goals for yourself. For example, Unit 1 should take you 13 hours. Perhaps you can sit down with your calendar and decide to complete Subunit 1.1 (a total of 3 hours) on Monday night, Subunit 1.2 (a total of 3 hours) on Tuesday night, Subunit 1.3 (a total of 3 hours) on Wednesday night, and so forth.
Tips/Suggestions: The course has been organized so that you will learn the concepts you need for the succeeding unit in the preceding unit. It is essential that you take notes while watching the videos and completing the readings as you progress through the course. In addition, take the homework, practice test, and practice work seriously.

Instructions: Watch this fiveminute video. Note that subunit 2.1.3.2 (compound inequalities, or tripartite) is very similar to 2.1.3.1 (solving linear inequalities), except for the way the former has been structured. Bear in mind that in the former, we will be balancing the left center and right. This means whatever you decide to do to the center in order to get the variable in question by itself, you have to do the same to the other two parts of the inequality. Notice also that if you divide or multiply through by a negative number, then you have to flip the inequality signs.

Link: Tyler Wallace’s Beginning and Intermediate Algebra, 2^{nd} edition: “Chapter 5, Section 5.7: Polynomials – Divide Polynomials” (PDF)
Instructions: Read this section. Dividing polynomials is just the same as the long division you learned in elementary school. It is also great practice in solidifying your skills in exponents and multiplication. Pay special attention to how the exponents work as place holders just as the digits in the 1s, 10s, 100s, and so forth, places did for us in elementary school. Note that this reading covers the material you need to know for subunits 3.4.2 and 3.4.3.

Unit 4: Factoring Polynomials
This unit expands on what you learned in Unit 3. In Unit 4, you will learn to factor the greatest common factor by grouping and other factoring methods. Because factoring and distribution are opposite actions, you will be able to determine whether you have factored correctly by going in the opposite direction, which is distributing through multiplication.
