Factor the expression shown below.

21x - 56

Question 2 options:

7(3x - 56)

21(x - 56)

7(3x - 8)

21(x - 35)

To factor the expression \( 21x - 56 \), we can start by finding the greatest common factor (GCF) of the two terms.

1. The GCF of 21 and 56 is 7.
2. Factoring 7 out of the expression:

\[
21x - 56 = 7(3x - 8)
\]

Thus, the correct factorization is:

\[
\boxed{7(3x - 8)}
\]
