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 a specific polynomial: ${-6x^3 - 12x^2 - 18x}$ . We will explore the different methods of factoring and provide a step-by-step guide on how to factor this polynomial.

What is Factoring?

Factoring is the process of expressing a polynomial as a product of simpler polynomials. It involves finding the factors of the polynomial, which are the numbers or expressions that multiply together to give the original polynomial. Factoring is an essential concept in algebra, as it allows us to simplify complex expressions and solve equations.

Methods of Factoring

There are several methods of factoring polynomials, including:

Greatest Common Factor (GCF): This method involves finding the greatest common factor of the terms in the polynomial.
Difference of Squares: This method involves factoring the difference of two squares.
Sum and Difference: This method involves factoring the sum or difference of two terms.
Grouping: This method involves grouping the terms in the polynomial and factoring out common factors.

Factoring the Polynomial

Now that we have discussed the different methods of factoring, let's apply them to the polynomial: ${-6x^3 - 12x^2 - 18x}$ .

Step 1: Find the Greatest Common Factor (GCF)

The first step in factoring the polynomial is to find the greatest common factor (GCF) of the terms. In this case, the GCF is -6x.

-6x^3 - 12x^2 - 18x = -6x(x^2 + 2x + 3)

Step 2: Factor the Quadratic Expression

The next step is to factor the quadratic expression: x^2 + 2x + 3. However, this expression cannot be factored further using simple factoring methods.

Step 3: Check the Answer Choices

Now that we have factored the polynomial, let's check the answer choices to see if any of them match our result.

A. ${6x(x^2 + 2x - 3)}$
B. ${-6x(-x^2 - 2x - 3)}$
C. ${-6x(x^2 + 2x + 3)}$
D. ${-6x(x^2 + 2x - 18)}$

Our result matches answer choice C: ${-6x(x^2 + 2x + 3)}$ .

Conclusion

Factoring polynomials is an essential concept in algebra that involves expressing a polynomial as a product of simpler polynomials. In this article, we have discussed the different methods of factoring and applied them to the polynomial: ${-6x^3 - 12x^2 - 18x}$ . We have found that the correct answer is ${-6x(x^2 + 2x + 3)}$ . We hope that this article has provided a clear and concise guide to factoring polynomials.
