2. Polynomials

A polynomial is an algebraic expression made up of variables, constants, and coefficients combined using operations like addition, subtraction, and multiplication. Examples include expressions such as 2x + 3, x² + 5x + 6, and x³ – 2x² + x. In this chapter, students learn about different types of polynomials based on their degree, such as linear, quadratic, and cubic polynomials.

 

The lesson also explains important concepts like the zeros of a polynomial, which are the values of the variable that make the polynomial equal to zero. Students learn about the relationship between the zeros and the coefficients of a polynomial and the division algorithm for polynomials. Understanding polynomials helps students develop strong algebraic skills and prepares them for more advanced topics in mathematics.
