**Factoring the Expression: A Step-by-Step Guide**

Introduction

In mathematics, factoring an expression is a process of expressing it as a product of simpler expressions. This is a crucial concept in algebra and is used extensively in various mathematical operations. In this article, we will focus on factoring the expression $60t + 40u - 50v$ . We will break down the process into manageable steps and provide a clear explanation of each step.

Understanding the Expression

Before we start factoring the expression, let's understand what it represents. The expression $60t + 40u - 50v$ is a linear combination of three variables: $t$ , $u$ , and $v$ . The coefficients of these variables are $60$ , $40$ , and $-50$ respectively. Our goal is to express this expression as a product of simpler expressions.

Step 1: Identify the Greatest Common Factor (GCF)

The first step in factoring an expression is to identify the greatest common factor (GCF) of the coefficients. In this case, the coefficients are $60$ , $40$ , and $-50$ . To find the GCF, we need to list the factors of each coefficient and identify the largest common factor.

Factors of $60$ : $1$ , $2$ , $3$ , $4$ , $5$ , $6$ , $10$ , $12$ , $15$ , $20$ , $30$ , $60$
Factors of $40$ : $1$ , $2$ , $4$ , $5$ , $8$ , $10$ , $20$ , $40$
Factors of $-50$ : $1$ , $2$ , $5$ , $10$ , $25$ , $50$

From the list of factors, we can see that the greatest common factor of $60$ , $40$ , and $-50$ is $10$ .

Step 2: Factor Out the GCF

Now that we have identified the GCF, we can factor it out of the expression. To do this, we divide each term in the expression by the GCF and multiply the result by the GCF.

$60t + 40u - 50v = 10(6t + 4u - 5v)$

In this step, we have factored out the GCF of $10$ from each term in the expression.

Step 3: Factor the Remaining Expression

Now that we have factored out the GCF, we can focus on factoring the remaining expression. In this case, the remaining expression is $6t + 4u - 5v$ . To factor this expression, we need to identify any common factors among the terms.

Factors of $6t$ : $1$ , $2$ , $3$ , $6$
Factors of $4u$ : $1$ , $2$ , $4$
Factors of $-5v$ : $1$ , $-1$ , $5$ , $-5$

From the list of factors, we can see that there are no common factors among the terms. Therefore, we cannot factor the remaining expression further.

Conclusion

In this article, we have factored the expression $60t + 40u - 50v$ using the greatest common factor (GCF) method. We identified the GCF of $10$ and factored it out of the expression. We then focused on factoring the remaining expression, but were unable to factor it further. The final factored form of the expression is $10(6t + 4u - 5v)$ .
