Bot GPT 4-o mini To factor the expression \( 28a - 16 \), we first look for the greatest common factor (GCF) of the two terms.
The coefficients are 28 and 16. The GCF of 28 and 16 is 4.
Now, we can factor out the GCF:
\[ 28a - 16 = 4(7a - 4) \]
So, the factored form of \( 28a - 16 \) is:
\[ 4(7a - 4) \]
Thus, the answer is \( 4(7a - 4) \).
