Introduction

In algebra, the Greatest Common Factor (GCF) is a fundamental concept used to simplify complex expressions. Factoring the GCF from an algebraic expression involves identifying the common factors among the terms and expressing each term as a product of the GCF and a remaining factor. In this article, we will explore how to factor the GCF from the given expression $$96x^2 + 88x$$.

Understanding the Greatest Common Factor (GCF)

The GCF of two or more numbers is the largest positive integer that divides each of the numbers without leaving a remainder. In the context of algebraic expressions, the GCF is the largest expression that divides each term of the expression without leaving a remainder.

Step 1: Identify the GCF of the Given Expression

To factor the GCF from the given expression $$96x^2 + 88x$$, we need to identify the common factors among the terms. The first step is to list the factors of each term.

Factors of $$96x^2$$: $$1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96, x, 2x, 3x, 4x, 6x, 8x, 12x, 16x, 24x, 32x, 48x, 96x$$
Factors of $$88x$$: $$1, 2, 4, 8, 11, 22, 44, 88, x, 2x, 4x, 8x, 11x, 22x, 44x, 88x$$

By examining the factors of each term, we can identify the common factors among the terms.

Step 2: Determine the GCF

The GCF of $$96x^2$$ and $$88x$$ is the largest expression that divides each term without leaving a remainder. By examining the common factors, we can determine that the GCF is $$8x$$.

**Answer 1: The GCF of $$96x^2$$ and $$88x$$ is $$8x$$.

Step 3: Factor the GCF from Each Term

Now that we have identified the GCF, we can factor it from each term of the expression.

$96x^2 = 8x \cdot 12x$
$88x = 8x \cdot 11$

By factoring the GCF from each term, we can express the original expression as a product of the GCF and the remaining factors.

**Answer 2: Each term written as a product, where one factor is the GCF, is $$8x \cdot 12x$$ and $$8x \cdot 11$$.

Conclusion

Factoring the GCF from an algebraic expression involves identifying the common factors among the terms and expressing each term as a product of the GCF and a remaining factor. By following the steps outlined in this article, we can factor the GCF from the given expression $$96x^2 + 88x$$ and simplify the expression.

Final Answer

The GCF of $$96x^2$$ and $$88x$$ is $$8x$$, and each term written as a product, where one factor is the GCF, is $$8x \cdot 12x$$ and $$8x \cdot 11$$.
