### Goals, Topics, and Objectives

Goal Statement

- To develop in students intermediate algebraic skills necessary for success in subsequent mathematics courses and other courses requiring mathematical skills.
- To develop in students the problem-solving skills needed to interpret, analyze and solve applied problems requiring intermediate-level algebraic skills.

Core Course Topics

- Factoring Polynomials
- Factor polynomials by factoring out the greatest common factor.
- Factor four-term polynomials by grouping.
- Factor trinomials.
- Factor perfect-square trinomials, the difference of two squares, and the sum and difference of cubes.
- Apply the appropriate factoring strategy to factor a polynomial.
- Solve quadratic equations by factoring.
- Solve application problems that can be modeled by quadratic equations.

- Rational Expressions and Rational Equations
- Simplify rational expressions.
- Perform algebraic operations of addition, subtraction, multiplication, and division on rational expressions.
- Simplify complex fractions.
- Solve rational equations algebraically.
- Solve rational equations for a specified variable.
- Solve application problems that can be modeled by rational equations.

- Functions and Graphs
- Write equations of lines using slope-intercept form and point-slope form, including parallel and perpendicular lines.
- Define a relation and express the domain and range of a relation in set builder or interval notation.
- Determine algebraically or graphically whether a relation is a function.
- Use function notation.
- Solve application problems that can be modeled by a linear function.

### Assessment and Requirements

Assessment of Academic Achievement

- All students will be required to complete a comprehensive final examination that assesses the learning of all course objectives.
- This final exam must be weighted in a manner so that this exam score is worth a minimum of fifteen percent (15%) of the final course grade. In selected semesters this final exam may be a common final exam administered to all sections of Math110.
- All students will be required to complete online homework. This online homework must be weighted in such a manner so that it is worth between six percent (6%) and twelve percent (12%) of the final course grade.
- Additional assessment of student achievement may include assignments, quizzes, and exams. All major exams should be designed in such a manner so that there is some portion in which graphing calculators are NOT allowed.

General Course Requirements and Recommendations

- Students must bring a scientific calculator to all class sessions.
- Access to an online homework management system is also required.
- Application problems must be covered in all mathematics courses. Every section in any course outline that includes application problems must be covered. Application problems must not only be included on chapter exams but also on the final exam.
