Question

Multiply the polynominal expression(b + 8) (3b - 6)

Answer 1

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

Here’s how you do it step-by-step:

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

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

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

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

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

Next, combine the like terms:
\[
3b^2 + (24b - 6b) - 48 = 3b^2 + 18b - 48
\]

Therefore, the product of the polynomial expression \((b + 8)(3b - 6)\) is:
\[
\boxed{3b^2 + 18b - 48}
\]
