NCERT Solutions for class 9 Maths Chapter 2 Exercise 2.2 Polynomials - PDF Download

NCERT solutions for class 9 mathematics chapter 2 ex 2.2 Polynomials refers to the questions related to the concept of the 'zero' of a polynomial. In other words, a polynomial must be equal to zero. After solving the equation, the value obtained is called the 'zero' of that specific polynomial or also called the root of that polynomial. 

The NCERT solutions class 9 maths chapter 2 ex 2.2 consists of 4 questions with their sub-parts and follows the simple logic of zeroes of a polynomial. It is important to remember that every real number should be equal to the zero of the given polynomial, and this should be keep in mind before solving the exercise.

NCERT solutions class 9 maths chapter 2 ex 2.2 provide a detailed PDF of each answer to the questions given in the exercise 2.2. These solutions help the students to score good marks in exams. Students can download the free PDF of NCERT solutions for ex 2.2 from eSaral website.

Topics Covered in Exercise 2.2 class 9 Mathematics Questions

Ex 2.2 class 9 maths questions covers topic zeroes of a polynomial. Students must understand the concepts of zeroes of a polynomial before solving the questions.

1. Zeroes of a Polynomial - In the case of a Polynomial, the variables for which the Polynomial is expected to be zero are referred to as the zeros of the Polynomial. It is also called the root of the polynomial. 

Polynomials with a value of zero are referred to as zero polynomials. Zero is defined as the point at which the whole polynomial reaches zero. 

Important Points

1. A zero of a polynomial need not be 0.
2. 0 may be a zero of a polynomial.
3. Every linear polynomial has one and only one zero.
4. A polynomial can have more than one zero.

Frequently Asked Questions

Question 1. What are constants and variables?

Answer 1. In any equation, constants are the numerical values associated with a variable (i.e., x, y). These values remain constant and do not change. Constants are used to determine the value of a variable. Conversely, variables are the values associated with a constant whose value must be determined. The value of a variable may vary in various situations.
