# Algebra

## GENERAL STUDIES

### Course Description:

Students will explore a variety of methods to solve equations, graph functions, use mathematical symbols to represent aspects of the physical world, and learn to communicate effectively using mathematical notation. The course covers the following topics: basic operations on polynomial expressions, solutions to linear and quadratic equations, linear functions (graphing, the slope and y-intercepts of lines, writing the equations of lines), systems of linear equations and inequalities, quadratic and exponential functions (graphing and their properties), properties of exponents, properties of rational and irrational numbers, and simplification of radical expressions. Also, since problem solving is an integral part of this course, students spend a considerable amount of time translating problems presented in written form to equivalent statements in mathematics. Then, the students find solutions to the problems and express the results in written form.

### Course Objectives:

• Students will translate, evaluate and simplify expressions, order of operation; Words to symbols and graph on a coordinate plane: ordered pairs, linear equations, linear inequalities, relations and functions.
• Students will solve equations and inequalities involving angle measures.
• Students will classify numbers into their appropriate systems.
• Students will calculate the probability and odds of a simple event using the results to predict the outcome of future events, and differentiate between odds and probability of a simple event.
• Students will recognize, analyze and extend patterns and recognize and use properties of Algebra.
• Students will formulate a linear equation or inequality given a word problem and vice versa.
• Students will determine if a relation is a function and evaluate a function for a given value and will identify the domain, range, and inverse of a relation showing the relation as sets of ordered pairs, tables, mappings and graphs.
• Students will perform the four basic operations on rational numbers.
• Students will determine the slope of a line given two points, a linear equation or a graph.
• Students will compare and order real numbers including square roots.
• Students will solve and graph compound inequalities.
• Students will determine the x and y intercepts of linear graphs from their equations and will solve linear equations and inequalities and graph solutions on a number line.
• Students will classify polynomials and determine the degree for any polynomial.
• Students will solve quadratic equations by factoring.
• Students will solve rational equations and identify and solve proportions using them in applications.
• Students will simplify polynomials using appropriate exponent rules and give answers in either descending or ascending order of exponents.
• Students will multiply polynomials using FOIL on the distributing property and appropriate exponent rules and give answers in either descending or ascending order of exponents.
• Students will factor out the GCF of a polynomial and factor polynomials completely using difference of two squares, perfect square trinomials, trial and error, or regrouping.
• Students will simplify rational expressions using the four basic operations and determine the undefined values.
