Welcome to the course material on Polynomials in General Mathematics. Polynomials play a fundamental role in algebra, providing a framework for understanding and solving a variety of mathematical problems. In this topic, we will delve into the analysis, manipulation, and application of polynomials of degrees not exceeding 3.

One of the key objectives of this course is to help you understand how to find the subject of a formula within a given equation. This involves rearranging equations to isolate a particular variable or term, enabling you to solve for specific quantities efficiently. By mastering this skill, you will be equipped to handle complex algebraic expressions with confidence.

Furthermore, we will explore the Factor and Remainder Theorems, essential tools in algebraic manipulation. These theorems allow us to factorize polynomial expressions effectively, breaking them down into simpler components for easier analysis. Understanding these theorems will enhance your problem-solving abilities and provide insights into the structure of polynomial functions.

Another crucial aspect we will cover is the multiplication and division of polynomials. You will learn strategies to multiply and divide polynomials of degree not exceeding 3, developing proficiency in handling polynomial operations. These skills are foundational in various mathematical fields, including calculus, algebra, and physics.

Moreover, we will discuss factorization techniques such as regrouping, difference of two squares, perfect squares, and cubic expressions. By applying these methods, you can factorize complex polynomial expressions efficiently. This proficiency will be invaluable in simplifying equations and solving polynomial-related problems with ease.

Additionally, we will delve into solving simultaneous equations involving one linear and one quadratic equation. This skill is essential in various real-world scenarios where multiple equations need to be solved simultaneously to determine unknown variables. You will learn techniques to approach such systems of equations systematically.

Lastly, we will explore the interpretation of graphs of polynomials, with a focus on polynomials of degree not greater than 3. Understanding polynomial graphs enables you to visualize mathematical functions, identify key features such as maximum and minimum values, and analyze the behavior of polynomial expressions graphically.
