Additional Resources:

For additional help, you may use any of the web sites listed.  The eCompanion site ( has all of the handouts for the course.  Students can post other useful web sites at the webliography page at our site.

PLEASE NOTE: It is expected that you will have access to a scientific calculator.  You will not be allowed to use a programmable, graphing, or statistical calculator on your final exam, nor will you be able to use a computer, so you will need to take a hand-held scientific calculator with you for the final exam.  I suggest you use the same calculator throughout the course.  Then you will be familiar with it and will avoid having to learn how to use a new calculator at final exam time.

Course Description:
MA 125 Intermediate Algebra Fundamentals of algebra. Topics include the real number system, basic operations of algebra, linear and quadratic equations, inequalities, functions and graphs, systems of equations. Additional considerations include radicals, rational functions, and basic analytic geometry. 3:0:3

Educational Philosophy:
The instructor's educational philosophy is one based on interaction through preparation (reading the material), lecture and demonstration, group exercises, practical application, and review.  After the first meeting, students are expected to have read the required material before coming to class, to attempt the homework problems from the previous week's topics, and to ask questions freely when a concept is not understood.  The first part of each session will be devoted to questions and answers.  Students should be prepared to show their understanding of the material through in-class demonstrations.

  Instructor Learning Outcomes

  1. 1. State and use basic terminology and symbols of the discipline appropriately
  2. 2. Solve linear equations and inequalities in one variable and verify solution(s)
  3. 3. Manipulate and simplify exponential expressions
Class Assessment:

Your final grade will be based on two quizzes, a final exam, homework and class participation.  Graded tests will be given back to the students for review; however, all graded materials must be returned to the instructor and filed for a period of 90 days after the end of the term. Grades for tests, homework, and the final will be posted on eCompanion (  This allows students to track their progress and the system automatically computes average score to date.

·         The Final Exam will be closed book, closed note exam.  Non-programmable, non-graphing calculators will be permitted.

o   Test #1:                      25%

o   Test #2:                      25%

o   Homework:                  25%

o   Comprehensive Final:    25%



92.5 – 100.0%:   A

85.0 -   92.4%:   B

77.5 -   84.5%:   C

70.0 -   77.4%:   D

 0.0 -    59.9%:   F

Late Submission of Course Materials:

Homework assignments, tests, and a final examination are due on the dates indicated in this syllabus.  If a student misses a homework, test or Final due to an excused absence, he/she must makeup the missed item before the end of the term.  If a homework, test or exam is missed and the absence is unexcused, the test may be taken and the grade received will be reduced by 10% for each week delayed.

Classroom Rules of Conduct:

For some students, idea of taking a mathematics course causes anxiety.  For others, it may have been years since they have studied math.  In this class, asking questions is encouraged.  Respect for those asking questions or feeling anxious about a new concept is a must.  During the class period, all cell phone and pager ringers must be turned off.  If you must take a call, quietly leave the classroom and talk in a breakroom, the entrance way, or outside the building.  Do not hold conversations in the hallway as this can disrupt other classes.  After class, all trash is to be removed and chairs placed under the tables.

Course Topic/Dates/Assignments:


In Week 1 we start the course with a review of fraction rules followed by an introduction to the properties and operations of Real Numbers.  We’ll also examine properties of exponents and roots, and then discuss the order in which mathematical operations are to be applied as we simplify algebraic expressions.

In Week 2 we'll begin learning techniques to solve linear equations in one variable followed by a discussion of formulas and how to solve problems using them.  Next we will apply those skills to real-life situations as we develop a general plan for solving application problems, and specific plans for certain types of problems.  We will also learn the processes of solving linear and compound inequalities and finish up the unit by learning how to solve absolute value equations and inequalities.

In Week 3, we'll be introduced to the Rectangular Coordinate System.  We will learn how to graph lines of equations in two variables.  We’ll discuss how to determine slope and how to use it to graph lines and find equations of lines.  We will also learn how to graph linear inequalities in two variables, and we’ll finish the unit by becoming acquainted with functions.

In Week 4 we will discover some new properties of exponents along with the properties of polynomial expressions.  We will learn how to use scientific notation as a tool for expressing very large and very small numbers.  We will exam methods for adding, subtracting, multiplying, and dividing polynomials.  We will expand our understanding of functions to include polynomial functions.

In Week 5 we will learn how to factor polynomials. Methods to be learned include: factoring by grouping, factoring trinomials, factoring perfect squares and perfect cubes. We finish the unit by focusing on a fundamental approach to factoring will be presented, and we will learn problem solving skills when the polynomial is part of an equation.

In Week 6 we start learning about rational expressions by examining their properties. From there we will begin the task of learning how to add, subtract, multiply, and divide rational expressions. We will learn two methods for simplifying complex fractions before we tackle solving equations involving rational expressions.

In Week 7, the properties of radical expressions are initially discussed before we take on the task of learning the procedures for simplifying, including the conversion from a radical expression to a rational exponential expression. Next we’ll learn how to add, subtract, multiply, and divide radical expressions. This is followed by a presentation of methods we will use for solving equations containing radical expressions.  We finish the unit by focusing on manipulating the polynomial equation into a particular format in a process known as completing the square. Once that process is learned we will use it to derive a generalized formula for solving all quadratic equations. 

In Week 8,we'll start by determining how to graphically find a solution set of two intersecting equations in two variables, known as a system of linear equations, followed by the procedure to solve a system algebraically.  We will finish the unit, and the course, with an introduction to Complex numbers.  We will learn the properties of these numbers, and how to apply mathematical operations on them.  During this final week of the course you will also complete the comprehesive Final Exam and the Course Evaluation.

Attendance Policy:
Instructors are required to maintain attendance records and to report absences via the online attendance reporting system.

  1. The instructor may excuse absences for valid reasons, but missed work must be made up within the semester/term of enrollment.
  2. Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties.
  3. In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the student will be administratively withdrawn, resulting in a grade of "F".
  4. A "Contract for Incomplete" will not be issued to a student who has unexcused or excessive absences recorded for a course.
  5. Students receiving Military Tuition Assistance or Veterans Administration educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the student.
  6. Report of a "F" grade (attendance or academic) resulting from excessive absence for those students who are receiving financial assistance from agencies not mentioned in item 5 above will be reported to the appropriate agency.
