Set 4

This is another pivotal unit in Math 9 as we will expand on the concept of Algebraic expressions and their operations that students learned in Math 8. Operations with Polynomials is the meat and potatoes in the language of Algebra. There are terminologies, syntax and rules that students need to learn to read, write, speak and compute in order to work with more complex algebraic expressions later course. This year we will learn to collect Like Terms, Add/Subtract Polynomials as well as basic multiplying and dividing of polynomials. Though these concepts are considered basic, we will be work through questions of varied difficulties and complexities in class. Next year students will carry on with more advanced multiplications and simplification of more complex series of Algebraic Expressions.

Our main goals in this unit are:

• Know the various parts of a Polynomial Expression.

• Be able to read, write, speak and compute Polynomials by understanding how to collect, add, subtract and multiply polynomials.

• Be able to understand and work with the basic concept of the distributive rule of algebraic expressions. a(b + c)

• To lay the foundation for the rules and ideas behind operations with Polynomials such that students will be better able to deal with more advance multiplication of Polynomials in later courses.

• To understand and appreciate that collect like terms is merely an extension of adding and subtracting integers. students can properly collect polynomials by applying prior knowledge they learned in a pervious unit.

• To understand and appreciate why we learned how to add, subtract, multiply and divide exponents to help us simplify Polynomial Expressions. By understand the fundamental concept of exponential notations, students can properly deal with the degree of a polynomials by applying prior knowledge they learned in a pervious unit.
