MTH 219 Week 4 Overview

In Week 1 we solved linear equations and set a solid foundation for algebra. In Week 2 we expanded to graphing linear equations and introduced polynomials. In Week 3 we learned to factor and graph polynomials. This week we focus on rational expressions, equations, and functions. A rational expression is a fraction with polynomials in the top and bottom halves of the fraction. Many real-life problems rely on rational expressions for the solution; for example, an artist uses proportions to scale up a drawing, or a manager can calculate how fast a job can be done by combining the rates of two employees. Even software development requires the use of rational expressions. This week we also use proportions, which are two fractions that are equal to one another. Because rational expressions are fractions that contain polynomials, proportions often come in the form of two rational expressions that are equal to one another. This week’s objectives are designed to allow you to simplify, analyze, and solve problems involving rational expressions and rational equations. Each week we have added more math tools and skills so that we can apply math to a greater variety of real-world applications. The concepts in this week require skills that you may have never used before. By focusing yourself to overcome the difficulties of learning the material, you increase your ability to think critically and overcome a greater variety of challenges in life. You are almost to the finish line for this course! Keep going strong!
