To expand the expression \(-56(9b - 12)\), you will distribute \(-56\) to both terms inside the parentheses.
Here’s the step-by-step process:
-
Distribute \(-56\) to \(9b\): \[ -56 \times 9b = -504b \]
-
Distribute \(-56\) to \(-12\): \[ -56 \times -12 = 672 \]
Now, combine both results: \[ -56(9b - 12) = -504b + 672 \]
So, the expanded expression is: \[ -504b + 672 \]
