Fundamentals of Linear Equations and Word Problems

Ever wondered about the formation of a Cartesian plane or the operations of linear equations? This course starts by introducing you to the formation of a Cartesian plane, which is done by a horizontal number line, called the x-axis, and a vertical number line called the y-axis. Learn about the various approaches that can be used to find the linear equation in algebra. This course explains how linear equations are solved graphically as well as algebraically using the substitution and elimination methods. Study the concept of second-order determinants from solving linear equations. Evaluate the process of using a traditional method to solve a system of literal linear equations in two or more variables. The material then shows how systems of linear equations are solved in three variables as well as how to solve these systems with three independent equations.

Having difficulty in graphing a linear inequality? This course succinctly explains the process of graphing linear inequalities as well as how to solve pairs of linear inequalities graphically. It unpacks the principles along with the methods of solving quadratic equations. Study examples of coin word problems and how to solve them using either a single or two variables. You will also learn about the relationship between three variables in distance calculation along with how to solve number problems using single or multiple variables. This course then teaches you the formulas for calculating perimeter and area from different word problems. Solve rectangular frame word problems and learn how the work word problems deal with accomplishing a job by two or more people or machines working at different rates.

Finally, you will discuss the concept of the parabola as it relates to quadratic inequalities as well as its turning point, the vertex. Explore different ways of determining the roots of quadratic equations. The material sheds light on the methods to graph quadratic equations. By completing this course, you will be able to solve quadratic equations using the completing the square method. You will also know how this method is used to establish a general formula for solving quadratic equations. The modules also discuss the relationship between discriminants and the quadratic formula along with their application to equations. This course is targeted at math students wanting to improve their algebra skills. Start today and improve your understanding of linear equations, word problems, and quadratic inequalities.
