To factor out the greatest common factor (GCF) of the polynomial \( 18g - 8 \), we first need to identify the GCF of the coefficients 18 and 8.
The factors of 18 are: \( 1, 2, 3, 6, 9, 18 \)
The factors of 8 are: \( 1, 2, 4, 8 \)
The highest common factor is \( 2 \).
Now we can factor out the GCF from the polynomial:
\[ 18g - 8 = 2(9g - 4) \]
So, the factored form of the polynomial is:
\[ 2(9g - 4) \]
