## PREREQUISITES

The prerequisite for Math 30 is completion of Math 20 with a grade of “C” or better,
or a qualifying score on the Math Competency Exam (MCE).

## COURSE DESCRIPTION

Designed to prepare students for Intermediate Algebra. Elementary Algebra
teaches simplifying algebraic expressions involving polynomials and rational terms; factoring; solving linear equations; solving quadratic equations using factoring; analyzing graphs of linear equations; and solving applied problems. This course will also include an introduction to algebraic operations with rational expressions.

## STUDENT LEARNING OUTCOMES

Upon successful completion of Math 30:

1. Students will be able to make use of factoring techniques, solve quadratic equations by factoring, and make use of factoring to simplify rational expressions.

2. Students will be able to translate English phrases into algebraic expressions and equations, and solve applied problems.

3. Students will be able to perform operations related to linear equations in two variables, solve systems of linear equations, and solve applications which can be modeled using systems of linear equations.

## COURSE OBJECTIVES

At the end of this course you should be able to…

(1) evaluate and simplify algebraic expressions using the rules of exponents, order of operations, combining like terms, and the distributive property
(2) add, subtract, multiply and divide using either monomials or polynomials;
(3) solve a linear equation or inequality and check the solution;
(4) analyze verbal problems, model with appropriate equations, substitute the known values, solve the resulting equations, and interpret the result in the context of the problem;
(5) factor polynomials;
(6) simplify, multiply and divide rational expressions;
(7) graph first degree equations in two variables;
(8) write an equation for a
given line, identify the slope of a line; and
(9) solve quadratic equations by factoring.
