# Elementary Algebra Topics

**Description**

A presentation of the basic concepts of algebra: linear equations in

one and two variables including systems and graphing , linear

inequalities, literal equations , integer exponents , polynomials ,

factoring, quadratic equations , and simple rational expressions .

Applications are included throughout the course.

MA091 meets 3 hours each week.

MA091A meets 5 hours each week
