The problem asks us to factor the linear expression $8x - 20$. The problem gives the factors of 8 and 20 and instructs us to find the greatest common factor (GCF) of 8 and 20. Then we need to divide each term in the expression $8x - 20$ by the GCF.

1. Problem Description

The problem asks us to factor the linear expression $8x - 20$. The problem gives the factors of 8 and 20 and instructs us to find the greatest common factor (GCF) of 8 and

2

0. Then we need to divide each term in the expression $8x - 20$ by the GCF.

2. Solution Steps

Step 1: Find the GCF of 8 and

2

0. The factors of 8 are 1, 2, 4, and

8. The factors of 20 are 1, 2, 4, 5, 10, and

2

0. The common factors of 8 and 20 are 1, 2, and

4. The greatest common factor (GCF) of 8 and 20 is

4.

Step 2: Divide the GCF out of each term.

$\frac{8x}{4} = 2x$

$\frac{20}{4} = 5$

Thus, $8x - 20 = 4(2x - 5)$.

3. Final Answer

GCF = 4

$8x - 20 = 4(2x - 5)$

The answer is 4.
