Bot GPT 4-o mini To factor the expression \(-6b - 15\) by dividing out the greatest common factor (GCF), we first need to identify the GCF of the coefficients \(-6\) and \(-15\).
The GCF of \(-6\) and \(-15\) is \(3\).
Now we can factor out \(-3\) from the expression:
\[ -6b - 15 = -3(2b + 5) \]
So, the factored form of \(-6b - 15\) is:
\[ -3(2b + 5) \]
