Answer 1

To simplify the polynomial \((b + 8)(3b - 6)\), we can use the distributive property (also known as the FOIL method for binomials).

1. First, distribute \(b\) to both terms in the second polynomial: \[ b \cdot 3b = 3b^2 \] \[ b \cdot (-6) = -6b \]

2. Next, distribute \(8\) to both terms in the second polynomial: \[ 8 \cdot 3b = 24b \] \[ 8 \cdot (-6) = -48 \]

3. Now, combine all the terms: \[ 3b^2 - 6b + 24b - 48 \]

4. Combine like terms (\(-6b + 24b = 18b\)): \[ 3b^2 + 18b - 48 \]

So, the simplified polynomial is: \[ 3b^2 + 18b - 48 \]

The correct response is: 3b² + 18b - 48.
