Introduction

Factoring polynomials is a fundamental concept in algebra that involves expressing a polynomial as a product of simpler polynomials. In this article, we will focus on factoring the polynomial $8r^2 + 12r$. Factoring polynomials is an essential skill in mathematics, and it has numerous applications in various fields, including physics, engineering, and economics.

What is Factoring?

Factoring a polynomial involves expressing it as a product of two or more polynomials. This is done by finding the greatest common factor (GCF) of the terms in the polynomial and then expressing the polynomial as a product of the GCF and the remaining terms. Factoring polynomials can be a challenging task, but with the right techniques and strategies, it can be made easier.

The Polynomial $8r^2 + 12r$

The given polynomial is $8r^2 + 12r$. To factor this polynomial, we need to find the greatest common factor (GCF) of the terms $8r^2$ and $12r$. The GCF of these terms is $4r$, which is the largest expression that divides both terms evenly.

Factoring Out the GCF

To factor out the GCF, we need to divide each term in the polynomial by the GCF. In this case, we divide $8r^2$ by $4r$ to get $2r$, and we divide $12r$ by $4r$ to get $3$. Therefore, the factored form of the polynomial is:

$$8r^2 + 12r = 4r(2r + 3)$$

Understanding the Factored Form

The factored form of the polynomial $8r^2 + 12r$ is $4r(2r + 3)$. This means that the polynomial can be expressed as the product of two simpler polynomials: $4r$ and $(2r + 3)$. The first polynomial, $4r$, is a linear polynomial, and the second polynomial, $(2r + 3)$, is a quadratic polynomial.

Why Factoring is Important

Factoring polynomials is an essential skill in mathematics because it allows us to simplify complex expressions and solve equations. By factoring polynomials, we can:

• Simplify complex expressions
• Solve equations
• Find the roots of a polynomial
• Understand the behavior of a polynomial

Real-World Applications of Factoring
