RATIONALE FOR COURSE:

This course continues to develop basic algebra concepts for application in college level mathematics courses. In addition, problem solving skills are continued to be developed that are useful in other disciplines.
_____________________________________________________________________________

COURSE DESCRIPTION:

This course continues the development of basic algebra concepts. Topics include factoring polynomials, solving polynomial equations, rational expressions, rational equations, radical expressions, radical equations, solving quadratic equations, graphing quadratic equations, and an introduction to the complex number system. This course is offered Satisfactory / Unsatisfactory only.
_____________________________________________________________________________

GENERAL COURSE GOALS:

1. Further students’ knowledge of mathematics as a symbolic language and
structure that is useful in solving real-world problems.

2. Develop a basic understanding of how to use algebraic skills to model
and solve real-world problems.

3. Develop students' ability to translate between English and Math.

4. Develop students' confidence to solve problems analytically.

5. Develop algebraic, graphical, and numerical techniques for solving
problems.
_____________________________________________________________________________

COURSE OBJECTIVES:
Upon completion of the course, the student should be able to:

1. Factor a polynomial by using appropriate methods: factoring out a common monomial factor, difference of two squares, difference and sum of two cubes, perfect trinomial square, other trinomial methods, and grouping.

2. Solve polynomial equations by factoring.

3. Use polynomial equations to solve appropriate application problems.

4. Add, subtract, multiply, and divide rational expressions.

5. Simplify complex rational expressions.

6. Solve equations involving rational expressions.

7. Use equations involving rational expressions to solve appropriate application problems.

8. Simplify expressions involving radicals and rational exponents.

9. Solve equations involving radicals and rational exponents.

10. Use equations involving radicals to solve appropriate application problems.

11. Simplify expressions involving complex numbers.

12. Solve quadratic equations in one variable using an appropriate method: extracting the square root, factoring, completing the square, or applying the quadratic formula.

13. Use the discriminant of a quadratic equation to determine the nature of solutions.

14. Complete the square as a means to transform a quadratic equation in two variables into standard form.

15. Graph a quadratic equation in two variables using the vertex, axis of symmetry and end behavior.

16. Use quadratic equations to solve appropriate application problems.

17. Solve equations that are quadratic in form. (As time permits.)

18. Solve quadratic inequalities analytically and interpret graphically. (As time permits.)

19. Communicate about algebra/mathematics both orally and in writing.
