Algebra

This chapter deals with the algebraic expressions, polynomials and its types, terms, factors and coefficients. It also discusses the simplification of algebraic expressions and arithmetic operations on algebraic expressions through solved examples.

This chapter establishes the concept of identities. A statement which is true for all the values of the variables involved is called identity. Here, we will learn about some standard identities through descriptive examples.

This chapter explains the concept of factorisation. We will learn to factorise an expression through the processes of taking common factors, grouping the terms and finding the difference between two squares. It also discusses the factorisation of quadratic trinomial.

This chapter explains how to solve the linear equations. We will learn about the ideas of replacement set and solution set. Linear inequations and their properties and representation of their solution set on the number line are also explained here in detail.
