NCERT Solutions for Class 10 Maths Chapter 1 Real Numbers
In Chapter 1 of Class 10 Maths, students are introduced to the basic concepts of real numbers, including rational and irrational numbers. The chapter begins with Euclid’s Division Lemma, which states that for any two positive integers a and b, there exist unique integers q and r such that
a = bq + r, where 0 ≤ r < b.
Based on this lemma, the Euclid’s Division Algorithm is explained, which helps students find the HCF of two positive integers. The chapter then introduces the Fundamental Theorem of Arithmetic, an important concept used to determine the LCM and HCF of numbers through their prime factorisation.
Further, students learn about rational and irrational numbers and understand the nature of the decimal expansion of rational numbers using relevant theorems. This chapter lays a strong foundation for number system concepts that are frequently tested in Class 10 board exams.
Topics Covered in Class 10 Maths Chapter 1 – Real Numbers
Fundamental Theorem of Arithmetic with examples
Proofs of irrationality of √2, √3, and √5
Steps to Find HCF Using Euclid’s Division Algorithm
Apply Euclid’s Division Lemma:
c = dq + r, where 0 ≤ r < dIf r = 0, then d is the HCF
If r ≠ 0, repeat the process with d and r
Continue until the remainder becomes zero; the final divisor is the HCF

NCERT Solutions for Class 10 Maths Chapter 2 Polynomials
In Class 10 Maths Chapter 2 Polynomials, students learn about polynomials based on their degree, such as linear, quadratic, and cubic polynomials. The chapter begins with an introduction to the degree of a polynomial and builds a strong foundation for understanding algebraic expressions.
This chapter includes four exercises, one of which is optional:
Exercise 2.1 focuses on finding the number of zeroes of a polynomial using graphs, based on the geometrical meaning of zeroes.
Exercise 2.2 covers the relationship between zeroes and coefficients of quadratic polynomials. Students are required to find the zeroes and, in some cases, construct the quadratic polynomial.
Exercise 2.3 introduces the Division Algorithm for Polynomials and includes problems based on polynomial division.
Exercise 2.4 (Optional) contains mixed questions from all the concepts covered in the chapter for overall revision.
Topics Covered in Class 10 Maths Chapter 2 Polynomials
Zeroes of a polynomial
Relationship between zeroes and coefficients of quadratic polynomials
Division Algorithm for polynomials
Division Algorithm for Polynomials Important Steps
Before starting the division, write both the dividend and divisor in standard form, that is, arrange their terms in descending order of degrees.
Step 1
Divide the highest-degree term of the dividend by the highest-degree term of the divisor to get the first term of the quotient. Continue the division process.
Step 2
Divide the highest-degree term of the new dividend by the highest-degree term of the divisor to obtain the next term of the quotient.
Step 3
Stop the division when the degree of the remainder becomes less than the degree of the divisor.
At this stage, the result follows the identity:
Dividend = Divisor × Quotient + Remainder
In general, for any two polynomials p(x) and g(x), where g(x) ≠ 0, there exist polynomials q(x) and r(x) such that:
p(x) = g(x) × q(x) + r(x)
where r(x) = 0 or degree of r(x) < degree of g(x).
This result is known as the Division Algorithm for Polynomials, and it is similar in concept to Euclid’s Division Algorithm studied in Chapter 1.

For a quadratic equation ax² + bx + c = 0, the value of b² − 4ac decides the nature of its roots:
Two distinct real roots, if b² − 4ac > 0
Two equal real roots, if b² − 4ac = 0
In this case, both roots are −b / 2aNo real roots, if b² − 4ac < 0
Since b² − 4ac determines the nature of the roots, it is called the discriminant of the quadratic equation.

In the following assignment, you will learn about the cumulative frequency distribution and construct cumulative frequency curves.
Topics Covered in NCERT Solutions for Class 10 Maths Chapter 13
Mean, median and mode of grouped data.
Mean by Direct Method and Assumed Mean Method only.
Important Formulas for Chapter 13 Statistics
There are three ways to determine the mean of the grouped data.
The direct method is: $\bar{x} = \dfrac{\sum_{i=1}^n f_i x_i}{\sum_{i=1}^n f_i}$
Where ∑fi xi is the total of observations from value i = 1 to n. ∑fi represents the number of observations from i = 1 to n.
Assumed Mean Method: $\bar{x} = a+\dfrac{\sum_{i=1}^n f_i d_i}{\sum_{i=1}^n f_i}$
The step deviation approach is: $\bar{x} = a+\dfrac{\sum_{i=1}^n f_i u_i}{\sum_{i=1}^n f_i} \times h$
Mode of grouped data:
Mode = $l+\dfrac{f_1-f_0}{2 f_1-f_0-f_2} \times h$

Classical definition of probability.
Simple problems on finding the probability of an event.
Important Formulas for Chapter 14 Probability
The theoretical probability (also known as classical probability) of an event E, denoted as P(E), is
$P(E)=\dfrac{\text { Number of outcomes favourable to } E}{\text { Number of all possible outcomes of the experiment }}$
We assume that the experiment's outcomes are equally likely.
The probability of a definite event (or certain event) is one.
The chance of an impossible event is zero.
The probability of an occurrence E is a number P(E), where 0 < P(E) ≤ 1.
An elementary occurrence is one that has only one possible conclusion. The total of the probability of all elementary occurrences in an experiment equals one.
