$$

Introduction

Factoring is a fundamental concept in algebra that involves expressing a quadratic expression as a product of simpler expressions. In this article, we will focus on factoring the quadratic expression $3n^2 - 11n + 6$. Factoring completely means expressing the quadratic expression in the form of $(ax + b)(cx + d)$, where $a$, $b$, $c$, and $d$ are constants.

Understanding the Quadratic Expression

Before we begin factoring, let's take a closer look at the quadratic expression $3n^2 - 11n + 6$. This expression consists of three terms: $3n^2$, $-11n$, and $6$. The first term, $3n^2$, is a quadratic term, while the second term, $-11n$, is a linear term, and the third term, $6$, is a constant term.

Factoring the Quadratic Expression

To factor the quadratic expression $3n^2 - 11n + 6$, we need to find two binomials whose product is equal to the given expression. We can start by looking for two numbers whose product is equal to the product of the quadratic and linear terms, and whose sum is equal to the coefficient of the linear term.

Step 1: Find the Factors of the Constant Term

The constant term in the quadratic expression is $6$. We need to find two numbers whose product is equal to $6$. The factors of $6$ are $1$ and $6$, $2$ and $3$. We can also use negative factors, such as $-1$ and $-6$, $-2$ and $-3$.

Step 2: Find the Factors of the Quadratic Term

The quadratic term in the quadratic expression is $3n^2$. We need to find two numbers whose product is equal to the product of the quadratic and linear terms. In this case, the product of the quadratic and linear terms is $3n^2 \cdot -11n = -33n^3$. We need to find two numbers whose product is equal to $-33n^3$.

Step 3: Find the Binomials

Now that we have found the factors of the constant term and the quadratic term, we can use them to find the binomials. We need to find two binomials whose product is equal to the given expression. We can start by using the factors of the constant term and the quadratic term to form two binomials.

Step 4: Check the Binomials

Once we have found the binomials, we need to check if their product is equal to the given expression. If the product of the binomials is equal to the given expression, then we have factored the quadratic expression completely.

Factoring the Quadratic Expression: A Step-by-Step Example

Let's use the steps above to factor the quadratic expression $3n^2 - 11n + 6$. We will start by finding the factors of the constant term.

Step 1: Find the Factors of the Constant Term

The constant term in the quadratic expression is $6$. We need to find two numbers whose product is equal to $6$. The factors of $6$ are $1$ and $6$, $2$ and $3$. We can also use negative factors, such as $-1$ and $-6$, $-2$ and $-3$.

Step 2: Find the Factors of the Quadratic Term

The quadratic term in the quadratic expression is $3n^2$. We need to find two numbers whose product is equal to the product of the quadratic and linear terms. In this case, the product of the quadratic and linear terms is $3n^2 \cdot -11n = -33n^3$. We need to find two numbers whose product is equal to $-33n^3$.

Step 3: Find the Binomials

Now that we have found the factors of the constant term and the quadratic term, we can use them to find the binomials. We need to find two binomials whose product is equal to the given expression. We can start by using the factors of the constant term and the quadratic term to form two binomials.

Step 4: Check the Binomials

Once we have found the binomials, we need to check if their product is equal to the given expression. If the product of the binomials is equal to the given expression, then we have factored the quadratic expression completely.
