RD Sharma Class 8 Solutions Chapter 7 - Factorization (Ex 7.5) Exercise 7.5 - Free PDF

The RD Sharma Class 8 Solutions Chapter 7 - Factorization will give students a clear understanding of Factorization and how it is used to simplify equations. By using the RD Sharma Class 8 Solutions, students will be able to understand number systems, expressions and equations better. Using these solutions, students will be able to factorize polynomials of degree 2 or 3.

What is Factorization?

Factorization is the process in which a number is written as a product of its prime factors. It is the process of decomposing a composite (non-prime) number into a product of one or more prime numbers that, when multiplied together, equal the original number.


Factorization Example:


The number 12 can be written as a product of its prime factors as follows: 


12 = 2 x 2 x 3


Therefore, 12 is composed of two 2s and three 3s.


Factorization of Polynomials:

When a polynomial is factored, the individual terms of the polynomial are written as a product of two or more binomials. The degree of the polynomial is the sum of the degrees of the binomials. By using this method, the degree of a polynomial with two terms is always 2. The degree of a polynomial with three terms is 3.


Factorization of Quadratic Equations:

A quadratic equation is an equation in the form ax²+bx+c=0, where a, b and c are real numbers, and x is the unknown. A quadratic equation can be factored into two linear equations. The solutions to the two linear equations will be the roots (or solutions) of the quadratic equation.


Factorization of Cubic Equations:

A cubic equation is an equation in the form ax³+bx²+cx+d=0, where a, b, c and d are real numbers, and x is the unknown. A cubic equation can be factored into two linear equations and a quadratic equation. The solutions to the three linear equations will be the roots (or solutions) of the cubic equation. Knowledge of the quadratic equation will be needed to solve the cubic equation.


The RD Sharma Class 8 Solutions Chapter 7 - Factorization will give students an idea about how Factoring is used to simplify equations. The solutions chapter will also help students understand number systems, expressions and equations. By using this chapter, students will be able to factorize polynomials of degree 2 or 3.
