Factor the expression completely 48x-42

To factor the expression completely, we can first find the greatest common factor (GCF) of the numbers 48 and 42.

The prime factorization of 48 is 2^4 * 3.
The prime factorization of 42 is 2 * 3 * 7.

To find the GCF, we take the product of the common prime factors raised to the lowest powers. In this case, 2^1 * 3^1 = 6.

Now we can factor out the GCF of 6 from the expression:

6(8x - 7)
