RS Aggarwal Solutions for Class 9 Chapter 3 “Factorisation-of-Polynomials”, A polynomial can be represented as a product of polynomials with its degree less than or equal to it. Every polynomial which is included to find the product is called a factor. The primary process which is involved in breaking a polynomial and making it as a product of its factor is called Factorisation of Polynomials. Factoring is a necessary process that helps us understand more about our equations. Through factoring, we rewrite our polynomials in a simpler form, and when we apply the principles of factoring to equations, we yield a lot of useful information. Factorisation-of-Polynomials chapter mainly contains problems based on methods of Factorisation. The Factorisation of the difference of two squares, Factorisation of quadratic trinomials, the square of a trinomial, cube of a binomial and Factorisation of sum or difference of cubes.
