RS Aggarwal Solutions for Class 8 Chapter 7 describes “Factorisation”, In Mathematics, factorisation or factoring is defined as the breaking or decomposition of an entity (for example a number, a matrix, or a polynomial) into a product of another entity, or factors, which when multiplied together give the original number or a matrix, etc. In the factorisation method, we reduce any algebraic or quadratic equation into its more straightforward form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable or an algebraic expression itself. As the Chapter is about factors, factoring is a useful skill required in real life. Common applications include dividing something into equal halves, exchanging money, comparing prices, understanding time and making calculations during travel.
