To factor the expression \(-24x + 64\), we first look for the greatest common factor (GCF) of the two terms.
The coefficients are -24 and 64. The GCF of 24 and 64 is 8.
Thus, we can factor out -8 from the expression:
\[ -24x + 64 = -8(3x - 8) \]
This is the complete factorization of the expression. Therefore, the correct response is:
\(-8(3x - 8)\)
