What is a Polynomial?
The terms Poly (meaning "many") and Nominal (meaning "terms") combine to form the term polynomial. An expression that consists of variables, constants, and exponents joined by mathematical operations like addition, subtraction, multiplication, and division (but not division by a variable) is called a polynomial. The expression is categorised as trinomial, binomial, or monomial depending on how many terms it contains. Here are some instances of variables, exponents, and constants:- Constants. Example: 1, 2, 3, etc.
- Variables. Example: g, h, x, y, etc.
- Exponents: Example: 5 in x 5 etc.
NCERT Solutions for Class 10 Maths Chapter 2 Ex 2.1 Polynomials
Below is the NCERT Solutions for Class 10 Maths Chapter 2 Ex 2.1 Polynomials -1. The graphs of y = p(x) are given in Fig. 2.10 below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.
Solutions:
Graphical method to find zeroes:-
The total number of zeroes in any polynomial equation = the total number of times the curve intersects the x-axis. (i) In the given graph, the number of zeroes of p(x) is 0 because the graph is parallel to the x-axis and does not cut it at any point. (ii) In the given graph, the number of zeroes of p(x) is 1 because the graph intersects the x-axis at only one point. (iii) In the given graph, the number of zeroes of p(x) is 3 because the graph intersects the x-axis at three points. (iv) In the given graph, the number of zeroes of p(x) is 2 because the graph intersects the x-axis at two points. (v) In the given graph, the number of zeroes of p(x) is 4 because the graph intersects the x-axis at four points. (vi) In the given graph, the number of zeroes of p(x) is 3 because the graph intersects the x-axis at three points.Benefits of Using NCERT Solutions for Class 10 Maths Chapter 2 Ex 2.1

NCERT Solutions for Class 10 Maths Chapter 2 Ex 2.1 FAQs
What are 2 facts about polynomials?
Like whole numbers, polynomials may be prime or factorable into products of primes. They may contain any number of variables, provided that the power of each variable is a nonnegative integer. They are the basis of algebraic equation solving.
What are the basic concepts of polynomials?
Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.
What are polynomials used for?
Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.
What is the zero of a polynomial?
Zeros of a polynomial can be defined as the points where the polynomial becomes zero as a whole. A polynomial having value zero (0) is called zero polynomial. The degree of a polynomial is the highest power of the variable x.
