NCERT Solutions for Class 9 Maths Chapter 2 - Polynomials
The chapter kicks off with the introduction of Polynomials. The concept of algebraic expression has been stated to relate to polynomials. There are various theorems in this chapter, namely The Remainder Theorem and Factor theorem. Examples of Zero and Non-zero polynomials have been explained in detail. The factorisation of polynomials by splitting the middle term and cubic polynomials have been explained with different values. Further, the chapter mentions the three terms of Polynomials and polynomials of two degrees, namely quadratic. The chapter states four kinds of algebraic identities in the end.
- Polynomials are a type of algebraic expression, and letters such as x,y,z etc. are used to denote the variables.
- There are different powers of polynomials, and the polynomial term with the highest power to determine the "degree of the polynomial."
- Various equations to solve both zero-polynomials and non-zero polynomials have been done in the chapter.
- The remainder theorem is explained by a simple example of dividing two numbers and the remainder, which is again divided until a number is obtained.
- Similarly, polynomials have been divided into the chapter by a monomial, denoted by "x."
- To factorise the cubic polynomials, first and last two terms are put in a group, and then common factors are derived.
- The chapter ends with the factorisation of an algebraic expression that uses reverse multiplication terminology.
