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

  1. Multiply the first terms: \[ b \cdot 3b = 3b^2 \]

  2. Multiply the outer terms: \[ b \cdot (-6) = -6b \]

  3. Multiply the inner terms: \[ 8 \cdot 3b = 24b \]

  4. Multiply the last terms: \[ 8 \cdot (-6) = -48 \]

Now, combine all these results: \[ 3b^2 - 6b + 24b - 48 \]

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

So the simplified multiplication of the polynomial \((b + 8)(3b - 6)\) is: \[ \boxed{3b^2 + 18b - 48} \]
