To expand the expression \(-56(9b - 12)\), we distribute \(-56\) to both terms inside the parentheses:
\[ -56 \cdot 9b - (-56) \cdot 12 \]
Calculating both products, we get:
\[ -504b + 672 \]
So, the expanded expression is:
\[ -504b + 672 \]
You can fill in the blanks as follows:
- The first term is −504b.
- The second term is +672.
Thus, the completed expanded expression is \(-504b + 672\).
