Final answer:
The expression 4x + 32 is factored by finding the greatest common factor which is 4, resulting in the factored form 4(x + 8).
Step-by-step explanation:
To factor the expression 4x + 32, we look for the greatest common factor (GCF) that both terms share. The number 4 is the GCF because it can divide both of the terms evenly. Thus, we take 4 out of each term:
Extract the GCF: 4(x + 8)
Check the factoring: 4 * x gives us the original 4x, and 4 * 8 gives us the original 32.
Therefore, the factored form of the expression 4x + 32 is 4(x + 8).
