To multiply the polynomials \((b+8)(3b−6)\), we can use the distributive property (also known as the FOIL method for binomials):
-
First: Multiply the first terms:
\(b \cdot 3b = 3b^2\) -
Outer: Multiply the outer terms:
\(b \cdot (-6) = -6b\) -
Inner: Multiply the inner terms:
\(8 \cdot 3b = 24b\) -
Last: Multiply the last terms:
\(8 \cdot (-6) = -48\)
Now, we combine all these results: \[ 3b^2 - 6b + 24b - 48 \]
Combining like terms (\(-6b + 24b\)): \[ 3b^2 + 18b - 48 \]
So the simplified expression is: \[ 3b^2 + 18b - 48 \]
The answer is A) 3b^2 + 18b - 48.
