Class 10 Maths Chapter 2 Solutions for State Boards
Class 10 Maths Chapter 2 Polynomials, covers various important concepts related to polynomial equations. Here are the main points to learn from this chapter. Understand what polynomials are and their characteristics. A polynomial is an algebraic expression consisting of variables, coefficients, and exponents, with non-negative integer exponents. Learn how to determine the degree of a polynomial based on the highest power of the variable term. Identify polynomials as constant, linear, quadratic, cubic, etc., based on their degree.
The ratioinalised textbooks issued by NCERT shows that there are only two exercises in chapter 2 of 10th mathematics. Earlier there were four exercises but the exercise 2.3 and 2.4 are deleted now. So, students have to practice only exercise 2.1 and 2.2 for the board exams. According to new syllabus and books issued for new session, the course structure of class 10 chapter 2 is as follows:
Zeros of a polynomial. Relationship between zeros and coefficients of quadratic
polynomials.
1. Now, Number of Exercises: 2
2. Number of Periods needed: 8
3. Weightage of Maths: 4 – 5
Know how to add and subtract polynomials by combining like terms. Understand the process of multiplying polynomials using the distributive property. Learn how to use the FOIL method for binomial multiplication (First, Outer, Inner, Last). Multiply a monomial by a polynomial and apply the distributive property. Recognize and apply formulas for special products such as the square of a binomial (a + b)² and the difference of squares (a² – b²).

Study polynomial division using long division and synthetic division methods.
Understand the concepts of divisors, dividends, quotients, and remainders. Learn techniques for factoring polynomials, including common factors, grouping, and the use of algebraic identities. Factorize quadratic trinomials of the form ax² + bx + c.
Familiarize yourself with important algebraic identities, such as (a + b)², (a – b)², and a² – b². Understand the Remainder Theorem, which relates the remainder of polynomial division to the value of the polynomial at a given point. Know the Factor Theorem, which states that (x – a) is a factor of a polynomial if and only if the polynomial evaluates to zero at x = a.
Learn how to use synthetic division for polynomial division, particularly for dividing by linear divisors of the form (x – a). Apply polynomial equations to real-world problems and mathematical modeling. Solve polynomial equations, both linear and quadratic, by factoring and applying the zero-factor property. Understand the graphical representation of polynomial functions and how to find the roots or solutions by analyzing the graph.
Summarize the key concepts, formulas, and techniques learned in this chapter for quick reference. These are the main points to learn from Class 10 Maths Chapter 2 Polynomials. It is a fundamental chapter in algebra that serves as a basis for more advanced topics in mathematics.
What are the important terms of 10th Maths Chapter 2 Polynomials?
What do you understand by a Polynomial as per Class 10 Maths Chapter 2?
An algebraic expression, in which variable(s) does (do) not occur in the denominator, exponents of variable(s) are whole numbers and numerical coefficients of various terms are real numbers, is called a polynomial.
In other words,
1. No term of a polynomial has a variable in the denominator;
2. In each term of a polynomial, the exponents of the variable(s) are non-negative integers and
3. Numerical coefficient of each term is a real number.
The terms of a polynomial, having the same variable(s) and the same exponents of the variable(s), are called like terms. A polynomial of degree 2 is called a quadratic polynomial. The degree of a non-zero constant polynomial is taken as zero. When all the coefficients of variable(s) in the terms of a polynomial are zeros, the polynomial is called a zero polynomial. The degree of a zero polynomial is not defined.
Do you know what is a monomial?
An algebraic expression or a polynomial, consisting of only one term, is called a monomial.
Which type of polynomial is called a binomial?
An algebraic expression or a polynomial, consisting of only two terms, is called a binomial.
Which type of algebraic expression is known as trinomial?
An algebraic expression or a polynomial, consisting of only three terms, is called a trinomial.

Zeros of Polynomials
The value(s) of the variable for which the value of a polynomial in one variable is zero is (are) called zero(s) of the polynomial. To verify the relationship between the zeroes and coefficients of a given quadratic polynomial, we can find the zeroes of p(x) by factorisation. By taking sum and product of these zeros, we can verify the following results.
Historical Facts about Polynomials
An elegant way of dividing a polynomial by a liner polynomial was introduced by Paolo Ruffin in 1809. His method is known as Synthetic division, which facilitates the division of a polynomial by a linear polynomial or binomial of the form x – a with the help of the coefficients involved.
Determining the zeros of polynomials, or finding roots of algebraic equations is among the oldest problems in mathematics. The modern way, we use today only developed beginning in the 15th century. Before that, linear equations were written out in words.
What is the History of the mathematical notations?
1. The use of the equal to (=) sign is in Robert Recorde’s book (The Whetstone of Witte in 1557). Plus sign (+) the sign of addition, minus sign (−) the sign of subtraction and the use of an alphabet for an unknown variable in Michael Stifel’s book (Arithemetica integra in 1544).
2. René Descartes, in 1637, introduced the concept of plotting the graph of a polynomial equation. Just because of him, the popularity of use of letters of the alphabet to denote constants and letters from the end of the alphabet (x, y, z, etc.) to denote variables (like 2x, 3y, 7z, etc.) in the general formula for a polynomial in one variable.
How to make good Practice in Class 10 Maths Chapter 2 Polynomials?
Polynomials are said to be one of the important sections of mathematics, especially for Algebra. They’re used in most of the equations and topics of numerical operation in standard 10 and higher also. It wouldn’t be wrong, if we say polynomials are Building Blocks of Maths expressions. Here we will learn about how to solve all exercises of 10th Maths chapter 2. Before learning about the polynomial equation, we have to know its significant importance that makes the topic more interesting. Many Maths process that are done in everyday life can be interpreted as polynomials. With the help of polynomial equations, one can calculate the grocery bill for small and even distance travelled by light in space.
