Download the official Linear Polynomials chapter from the new Ganita Manjari textbook here. This Class 9 Maths Book PDF Chapter 2 Linear Polynomials is the exact NCERT file for the 2026-27 session. Use it to learn the algebra of terms, degrees, and straight-line graphs straight from the source before your Class 9 annual exam.
- Length: the official chapter PDF runs to 25 pages of text, graphs, and exercises.
- What it teaches: polynomials, the zero of a linear polynomial, and the line y = ax + b.
- New book: this is the 2026-27 Ganita Manjari book, so Linear Polynomials is now Chapter 2.
This is the original NCERT chapter file, matched to the current 2026-27 syllabus, so every page, graph, and exercise number is exactly what your teacher uses in class.
What's in the Class 9 Maths Linear Polynomials NCERT Book PDF?
The Class 9 Maths Book PDF Chapter 2 Linear Polynomials is a 25-page chapter. It begins with the basic language of algebra, terms, coefficients, and degree, then focuses on linear polynomials of the form ax + b. The file then links these to number patterns and straight-line graphs, and closes with six exercise sets and an End-of-Chapter set.

Linear Polynomials Section-by-Section Overview
The chapter builds from words to graphs in a steady order. The table below maps each section to what you will learn.
| Section | Topic | What you will learn |
|---|---|---|
| Meet Polynomials | Terms and degree | Variables, coefficients, constants, and what makes an expression a polynomial |
| Linear Polynomials Up Close | Value and zero | The standard form ax + b and how to find its zero |
| Linear Patterns and Sequences | The nth term | Turning a growing or shrinking pattern into a rule |
| Linear Relationships | The line y = ax + b | Building a relation between two quantities, like temperature conversion |
| Straight-Line Graphs | Plotting lines | Lines through the origin, parallel lines, and the y-intercept |
| Word Problems | Fare and pattern sums | Using linear polynomials to solve real fee and number problems |
Solved Examples and Exercises in Linear Polynomials
The chapter gives in-text solved examples first, then several exercise sets to practise. Read the solved examples before you try each set.
- Exercises 2.1 to 2.6: six sets covering terms, zeros, patterns, relations, and graphs.
- End-of-Chapter Exercises: mixed problems that pull the whole chapter together.
- In-text solved examples: step-by-step models placed through the chapter text.
What Changed in the 2026-27 Linear Polynomials Chapter
This chapter comes from the new Ganita Manjari book, which replaces the old 15-chapter NCERT Maths book. The new book is activity-based, so polynomials are taught through patterns, tables, and graphs rather than dry definitions. The old book split this content across separate polynomial and linear-equation chapters. Now the linear case leads as Chapter 2, giving you one clear thread from a term to a line.
How to Read the Linear Polynomials Chapter
Read the Class 9 Maths Book PDF Chapter 2 Linear Polynomials with graph paper ready. Skim once to see the flow, then read slowly and draw each line as it appears. Work through the solved examples, and only then try the exercises. This skim, then detail, then examples, then exercises order keeps the algebra clear.
