Factor each expression. If the expression cannot be factored, write cannot be factored. Use algebra tiles if needed. 18x + 6
To factor the expression 18x + 6, we can look for the greatest common factor (GCF) of the two terms, which in this case is 6.
Step 1: Find the GCF
The GCF of 18x and 6 is 6.
Step 2: Divide each term by the GCF
Dividing 18x by 6 gives us 3x, and dividing 6 by 6 gives us 1.
Step 3: Write the factored expression
We can now express 18x + 6 as the product of the GCF and the remaining terms:
(6)(3x + 1)
So the factored form of the expression 18x + 6 is 6(3x + 1).
