To multiply the polynomials \( (b+8)(3b−6) \), we can use the distributive property (also known as the FOIL method for binomials).
Let's perform the multiplication step-by-step:
1. **Distribute \( b \) to both terms in \( (3b - 6) \)**:
\[
b \cdot 3b = 3b^2
\]
\[
b \cdot (-6) = -6b
\]
2. **Distribute \( 8 \) to both terms in \( (3b - 6) \)**:
\[
8 \cdot 3b = 24b
\]
\[
8 \cdot (-6) = -48
\]
3. **Combine all the results**:
\[
3b^2 - 6b + 24b - 48
\]
4. **Combine like terms**:
\[
3b^2 + ( -6b + 24b) - 48 = 3b^2 + 18b - 48
\]
So, the simplified result is:
\[
3b^2 + 18b - 48
\]
Thus, the correct answer is:
**3b^2 + 18b - 48**
