To factor the expression \(8y + 18\), we first identify the greatest common factor (GCF) of the two terms.
The coefficients are 8 and 18. The GCF of 8 and 18 is 2.
Now, we can factor out the GCF from the expression:
\[ 8y + 18 = 2(4y + 9) \]
Thus, the factored form of \(8y + 18\) is
\[ 2(4y + 9) \]
This shows the expression as a product with a whole number greater than 1.
