Explanation
[tex]-24-12w[/tex]Step 1
factorize each term
[tex]\begin{gathered} -24=-6\cdot4 \\ -12w=-6\cdot2w \end{gathered}[/tex]replace,
[tex]\begin{gathered} -24-12w=-6\cdot4-6\cdot2w \\ \text{the common factor is -6,so} \\ -24-12w=-6\cdot4-6\cdot2w=-6(4+2w) \end{gathered}[/tex]so, the answer is
[tex]C\text{. }-6(4+2w)[/tex]I hope this helps you.
