In Chapter 2 of NCERT Solutions for Class 9 Maths, students are introduced to polynomials, expressions consisting of variables and coefficients. As well as their factorization, properties such as addition, subtraction, division, and multiplication of polynomials are also taught in this chapter. This chapter also proves the Factor and Remainder Theorem using these polynomials.
Topics Covered
The concept of polynomial functions goes way back to perhaps Babylonians times, since for example as simple a need of computing the area of a square y = x 2 is a polynomial, and is needed in buildings and survey, fundamental to core civilization.
The Pythagorean theorem x 2 + y 2 = z 2 is also a polynomial equation, and much basic number theory have been expressed algorithmetically in Greek or pre-Greek era.The modern concept of polynomial as a function of integer powers and their symbolic manipulation is developed in 1600s and 1700s. Finding solutions of polynomials as ready-made formulas is a spectacular chapter in the history of mathematics.

The Chapter discusses the cartesian plane, the coordinates of a point in the 'xy' plane, and several other terms associated with coordinate geometry.
Topics Covered
René Déscartes, the great French mathematician of the seventeenth century, liked to lie in bed and think! One day, when resting in bed, he solved the problem of describing the position of a point in a plane. His method was a development of the older idea of latitude and longitude. In honour of Déscartes, the system used for describing the position of a point in a plane is also known as the Cartesian system.
Sub topics covered in this chapter are The Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane, notations, plotting points in the plane, graph of linear equations as examples; focus on linear equations of the type ax + by + c = 0 by writing it as y = mx + c and linking with the chapter on linear equations in two variables.

In Chapter 4, students get familiar with coordinate geometry and learn how to plot the graph of a linear equation with two variables. Linear equations in two variables demonstrate the connection between two variables and how this relates to their graphical representation. These equations come with two solutions, producing a line when plotted. NCERT solutions for class 9 maths Chapter 4 linear equations in two variables are created with exercises based on writing linear equations, discovering their answers, plotting them, and seeing how they form lines parallel to x and y axes.
Topics Covered
An equation is simply the mathematical way to describe a relationship between two variables. The variables may be physical quantities, perhaps temperature and position for instance, in which case the equation tells us how one quantity depends on the other, so how the temperature varies with position.
The simplest kind of relationship that two such variables can have is a linear relationship. This means that to find one quantity from the other you multiply the first by some number, then add another number to the result. Put mathematically, if we call the quantities x and y, then they are related by the equation? y = mx + c, where we can choose any values for m and c.
This is a linear equation. Fortunately, in real physical problems, quantities often are related linearly, so this equation is very commonly used.This chapter covers- Recall of linear equations in one variable. Introduction to the equation in two variables.

In Chapter 8, you will learn about quadrilaterals and their various properties. A quadrilateral is a figure obtained by joining four distinct points on a plane. Students are provided with in-depth knowledge about the topic in this chapter.
Topics Covered
There are three topological types of quadrilaterals convex quadrilaterals concave quadrilaterals and crossed quadrilaterals. A quadrilateral with two sides parallel is called a trapezoid, whereas a quadrilateral with opposite pairs of sides parallel is called a parallelogram.
A special type of quadrilateral is the cyclic quadrilateral, for which a circle can be circumscribed so that it touches each polygon vertex. Another special type is a tangential quadrilateral, for which a circle can be inscribed so it is tangent to each edge. A quadrilateral that is both cyclic and tangential is called a bicentric quadrilateral.
(Prove) The diagonal divides a parallelogram into two congruent triangles. (Motivate) In a parallelogram opposite sides are equal and conversely. (Motivate) In a parallelogram opposite angles are equal and conversely. (Motivate) A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and equal. (Motivate) In a parallelogram, the diagonals bisect each other and conversely. (Motivate) In a triangle, the line segment joining the mid points of any two sides is parallel to the third side and (motivate) its converse.

You have studied the concept of quadrilaterals and triangles, and now you will study specific quadrilaterals, viz. parallelograms and triangles in relation to the calculation of their area. In this chapter, students learn the formula for area calculation and the relationship between different geometric figures.
Topics Covered
First of all, obviously, equally oriented, congruent parallelograms have the same area, because they can be made to cover each other. An examination of two symmetric parallelograms, which have the same area, because they will cover each other on reflection, is a step in the right direction. The area of a parallelogram is obtained by sub-division into two congruent triangles. The area of a trapezoid also involves its being cut up by a diagonal into two triangles.
Review concept of area, recall area of a rectangle. Prove Parallelograms on the same base and between the same parallels have the same area. Motivate Triangles on the same base and between the same parallels are equal in area and its converse.

Various concepts, such as the angle subtended by the arc of a circle, cyclic quadrilaterals, etc., are also discussed in this chapter of Class 9 Maths. NCERT Solutions for Class 9 Maths Chapter 10 Circles can help students develop logical thinking and problem-solving skills.
Topics Covered
Topics Covered in Class 9 Maths Chapter 10 Circles:
Examples include definitions of circle-related concepts, radius, circumference, diameter, chord, arc, and subtended angle.
The circle has been known since before the beginning of recorded history. It is the basis for the wheel which, with related inventions such as gears, makes much of modern civilization possible. In mathematics, the study of the circle has helped inspire the development of geometry and calculus.
Circles are simple closed curves which divide the plane into an interior and an exterior. The circumference of a circle is the perimeter of the circle, and the interior of the circle is called a disk. An arc is any connected part of a circle. A circle of infinite radius is considered to be a straight line. A circle with zero radius is considered as a point.
Through examples, arrive at definitions of circle related concepts, radius, circumference, diameter, chord, arc, subtended angle.

Topics Covered
(Much time will be devoted to group and individual activities to motivate the concept;
In investigating weighing, and sorting and finding an efficient code, you may note a common thread. In each case, and in many others that we will encounter later, we start with a (usually large) number of possible situations, and are interested in determining the true situation from among them. Thus we have devised schemes for doing so in the contexts mentioned.
Probability theory, which by the way was developed initially in the study of gambling schemes, is intended to provide a framework for modeling problems of this kind, with the aim of providing information about what we can “expect” to happen in each context.
This is done by defining a Sample Space whose points or elements are the possible situations, each one of which is given a weight or probability according to the proportion of the time we expect it to be the true situation.Then we determine what to “expect” as the answer to some question, by representing the answer as a function defined on the points of the sample space, and averaging that function over them.
In most contexts, including gambling and all that we have considered so far, the potential situations can be represented by strings of binary bits (or ternary symbols, in the case of weighing). In the following discussion we assume that our sample space consists of points each of which is such a bit string.
