Recognise the appropriate identity. Rewrite the given expression in the form of the identity. Write the factors of the given expression using the identity..

Factorisation using Identities - Recall the following identities for finding the products: Observe that the LHS in the identities are all factors and the RHS are their products. Thus, we can write the factors as follow..

Recall the following identities for finding the products: Observe that the LHS in the identities are all factors and the RHS are their products. Thus, we can write the factors as follows: From the above identities we observe that a given expression, which is in the form of an identity can be writte..

Let x + y = u Substitute x + y for u, Hence, ..

Introduction - This chapter takes us much further and adds to our already existing knowledge about Ratio and Proportion. We will have to use many of the algebraic manipulations learnt earlier, use them with expertise to solve problems in this chapt..

Introduction - We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figure..
