Introduction

Factoring expressions is a fundamental concept in algebra, and it plays a crucial role in solving equations and inequalities. In this article, we will explore how to factor the expression $8x + cy$ and determine the value of $c$ that would make the expression completely factored.

Understanding the Expression

The given expression is $8x + cy$, where $x$ and $y$ are variables, and $c$ is a constant. To factor this expression, we need to find a common factor that can be factored out from both terms.

Factoring Out the Greatest Common Factor (GCF)

The greatest common factor (GCF) of $8x$ and $cy$ is $2$. However, we cannot factor out $2$ from both terms because it is not a common factor of both terms. The GCF of $8x$ is $8$, and the GCF of $cy$ is $c$. Therefore, we need to find a value of $c$ that would make the GCF of both terms equal to $4$.

Finding the Value of c

To find the value of $c$, we need to determine what value of $c$ would make the GCF of $8x$ and $cy$ equal to $4$. Since the GCF of $8x$ is $8$, we need to find a value of $c$ that would make the GCF of $cy$ equal to $4$. This means that $c$ must be a factor of $4$.

Factors of 4

The factors of $4$ are $1$, $2$, and $4$. However, we need to find a value of $c$ that would make the GCF of $8x$ and $cy$ equal to $4$. This means that $c$ must be equal to $4$.

Conclusion

In conclusion, the value of $c$ that would make the expression $8x + cy$ completely factored is $4$. This is because $c$ must be a factor of $4$ to make the GCF of $8x$ and $cy$ equal to $4$.

Final Answer

The final answer is $\boxed{4}$. However, since the options provided are $2$, $7$, $12$, and $16$, we need to re-evaluate our answer.

Re-Evaluation

Upon re-evaluation, we realize that we made an error in our previous conclusion. The value of $c$ that would make the expression $8x + cy$ completely factored is not $4$, but rather a value that would make the GCF of $8x$ and $cy$ equal to $4$. This means that $c$ must be a multiple of $4$.

Multiple of 4

The multiples of $4$ are $4$, $8$, $12$, $16$, and so on. However, we need to find a value of $c$ that would make the GCF of $8x$ and $cy$ equal to $4$. This means that $c$ must be equal to $4$ or a multiple of $4$ that is also a factor of $cy$.

Factor of cy

The factor of $cy$ is $c$. Therefore, we need to find a value of $c$ that would make the GCF of $8x$ and $cy$ equal $4$. This means that $c$ must be equal to $4$ or a multiple of $4$ that is also a factor of $cy$.

Multiple of 4 that is a Factor of cy

The multiple of $4$ that is a factor of $cy$ is $4$. Therefore, the value of $c$ that would make the expression $8x + cy$ completely factored is $4$.
