Introduction

Factoring the greatest common factor (GCF) of an algebraic expression is a fundamental concept in algebra that helps simplify complex expressions and solve equations. In this article, we will focus on factoring the GCF of the given expression: $12x^3y + 6x^2y^2 - 9xy^3$ . We will explore the different options provided and determine the correct factorization of the GCF.

Understanding the Greatest Common Factor (GCF)

The GCF of an algebraic expression is the largest expression that divides each term of the expression without leaving a remainder. In other words, it is the product of the common factors of the terms in the expression. To factor the GCF, we need to identify the common factors of the terms and multiply them together.

Factoring the GCF of the Given Expression

Let's analyze the given expression: $12x^3y + 6x^2y^2 - 9xy^3$ . We can see that each term has a common factor of $3xy$ . Therefore, we can factor out the GCF as follows:

12x^3y + 6x^2y^2 - 9xy^3 = 3xy(4x^2 + 2xy - 3y^2)

Evaluating the Options

Now that we have factored the GCF, let's evaluate the options provided:

Option A: $3x^2y(4x + 2xy - 3)$
Option B: $3xy(4x + 2xy - 3y^2)$
Option C: $3xy(4x^2 + 2xy - 3y^2)$
Option D: $3x^2y(4x^3y - 2x^2y^2 - 3xy^3)$

We can see that only Option C matches our factored GCF.

Conclusion

In conclusion, factoring the GCF of an algebraic expression is a crucial concept in algebra that helps simplify complex expressions and solve equations. By identifying the common factors of the terms and multiplying them together, we can factor the GCF and simplify the expression. In this article, we factored the GCF of the given expression: $12x^3y + 6x^2y^2 - 9xy^3$ and determined that the correct factorization of the GCF is $3xy(4x^2 + 2xy - 3y^2)$ .
