## Important Topics For NCERT Exemplar Class 9 Maths Solutions Chapter 2: Polynomials

Problems in NCERT Exemplar Class 9 Maths Exemplar Chapter 2 are going to discuss different topics associated with polynomials. In the word ‘polynomials’, ‘poly’ means ‘many’ and ‘nomials’ means ‘term’. In terms of mathematics, a polynomial contains variables that are known as coefficient as well as indeterminates. A coefficient involves different operations like additions, subtraction, no negative integer exponent of variables as well as multiplications.

**Polynomials**

Polynomials refer to the expressions that contain one or more terms along with a non-zero coefficient. Polynomials can have more than one number of terms. In a polynomial, each and every expression is referred to as a term.

**Constant Polynomials**

When the real numbers are expressed as polynomials like 367 are also polynomials that do not contain any variables these are known as constant polynomials. Also, a constant polynomial 0 zero is known as zero polynomial.

**Degree of polynomials**

The highest power of the polynomial is known as the degree of the polynomial

**Types of Polynomials**

- Linear polynomials consist of degree 1
- Quadratic polynomial consist of degree 2
- Cubic polynomial consists of degree 3

**Polynomial Function**

A polynomial function is a function that involves only no negative integers powers or only the positive integers exponents of any variable in an equation like a quadratic equation, cubic equation, etc. you can also call a polynomial function as a polynomial expression that is defined by its degree.

You can represent a polynomial as p{x}. The degree of a polynomial function is essential to understand as it helps in identifying the behaviour of the function p[x] when x is very large.

**Types of Polynomials Functions**

There are different polynomial functions that are based on the degree of the polynomial and most common are

- Zero polynomial function
- Linear polynomial function
- Quadratic polynomial function
- Cubic polynomial function
- Quartic polynomial function

### Exercise Discussion of NCERT Maths Exemplar Solutions Class 9 Chapter 2- Polynomials

- The first exercise of NCERT Exemplar problems with solutions for class 9 maths chapter 2 begins with the question in which you need to identify if the polynomial is in 1 variable or not. You have to state the right reason for your answer. This exercise also tets your understanding if you can identify the coefficient degree and if you can classify the types of polynomials.
- In the second exercise, you have to find the values of the polynomials in different questions as these questions check your analytical skills.
- In the exercises 2.3.and 2.4, you will be checked if you can find, you will be checked that you can identify if a polynomial had the given factor. Also, you will be asked to find the values of K when the facto will be given
- Exercise 2.5 identify that you will be able to use the identities in the questions and if you will be able to factorise every question given. All the questions of the exercises are going to help you learn all the basics of the chapters.
