## Important Topics of RD Sharma Class 8 Solutions for Chapter 7 – Factorization

**Factorization **

As the name of the chapter suggests you will begin by having an introduction to the concept of factorization. An algebraic expression is said to be factorized when we write the products of that expression.

**Common Factor Method **

In this chapter, you will learn about a method of factorization called the common factor method. This is the most basic technique of factorizing an expression. Here you basically find the value that is common to all the terms of the expression i.e. the factors can be reduced by that term. Then the remaining terms are combined using the distributive law and the factors are obtained.

**Factorization by Algebraic Formulas **

You would have learnt about basic algebraic formulas like (a-b)^{2 }and a^{2}–b^{2}. Basically, you need to detect whether or not the given algebraic expression falls in the frame of these equations. In case if they are provided in the same form, you need to apply this formula and solve them further.

Along with these methods, you will also learn about other methods of factorization like the regrouping method, the method of finding coefficients and splitting of the middle term.
