In the first exercise, students will learn how to check whether the given equation is quadratic or not and representing the same. A short example is given to explain how we can deal with real-life problems with quadratic equations. We all have dealt with so many real-life situations where we come across quadratic equations. Mathematics NCERT Grade 10, Chapter 4 Quadratic Equations. NCERT Solutions for Class 10 Maths Chapter 4 - Quadratic Equations.

In the end, an optional exercise and key points of the chapter are given. Concept of upstream and downstream is cited in this section. Next exercise is based on the topic- Equations Reducible to a Pair of Linear Equations in Two Variables. Here the students have to check whether the given lines intersect at a point, are parallel or coincident.ДЄfter that, Algebraic Methods of Solving a Pair of Linear Equations is explained. Here the concept of the inconsistent and consistent pair of linear equations is explained. Next section is about the topic- Graphical Method of Solution of a Pair of Linear Equations. The very first exercise contains 3 problems which are based on the concept on how a given situation can be represented algebraically and graphically. Mathematics NCERT Grade 10, Chapter 3- Pair of linear equations in two variables: This chapter starts with an introduction followed by a short description on the topic Pair of linear equations in two variables.

Moving further, students will learn about division algorithms for polynomials.ДЄdditionally, an optional exercise is given but that exercise is just for practice and not given from the examination point of view.ДЇor a perfect finish, a few important points are given to give a summary of the chapter. In the next section, the relationship between zeroes and coefficients of a polynomial is explained.Д®xercise 2.2 consists of questions in which students need to find the sum and product of zeroes of the given polynomial. Parabolas are introduced in this section.ДЄfter that, solved examples are given to show how the number of zeroes can be determined by using the graphical method.Д®xercise 2.1 is based on the same concept. Various graphs are shown to explain how plotting of equations is done. The next section describes the geometrical meaning of the zeroes of a polynomial. Mathematics NCERT Grade 10, Chapter 2, Polynomials chapter starts by citing about degrees of polynomial and differentiation of polynomials based on its degree.

Thus, students need to understand these theorems thoroughly.ДЄt the end of the chapter, for recapitulation, a summary of the chapter is provided. 3 theorems are required to solve questions of exercise 1.4. Moving further to the next exercise which is based on topic- revisiting rational numbers and their decimal expansions. Exercise 1.3 is a short exercise consisting of 3 questions. Various theorems are given to make the student understand that how a specific number can be proved irrational. The next exercise is based on the topic of revisiting irrational numbers. Further going deep into this topic, two very important properties of a real number are discussed in the first two sections namely:Д®uclid's division algorithm consists of a brief description of Euclid's division lemma. A partial discussion was done in class 9th about real numbers. Mathematics NCERT Grade 10, Chapter 1, REAL NUMBERS: This chapter starts with an introduction about real numbers.
