 # ALGEBRA 2, PART 1

## Price: \$95 | Credits: 5 | Dept: Math

This course builds upon the body of knowledge and skill set learned from Algebra 1 and moves beyond. The course is the first half of Algebra 2 and includes the topics: Equations and Inequalities, Linear Functions & Inequalities, Systems of Linear Equations and Inequalities, Matrices and Determinants, Quadratic Equations, Graphing Quadratic Functions, Polynomials, Rational Expressions. This is the first semester in a two semester complete Algebra 2 course.

Upon completion of this course, the student is awarded 5 credits. Each credit corresponds to 15 hours of study. Of course, some students work more quickly than others, and some can devote more hours to study, so some students are able to complete the course in an accelerated rate.
