To multiply the polynomials (3x−1)(2x+4), we apply the distributive property (also known as the FOIL method for binomials):
1. **First**: Multiply the first terms:
\(3x \cdot 2x = 6x^2\)
2. **Outer**: Multiply the outer terms:
\(3x \cdot 4 = 12x\)
3. **Inner**: Multiply the inner terms:
\(-1 \cdot 2x = -2x\)
4. **Last**: Multiply the last terms:
\(-1 \cdot 4 = -4\)
Now, we combine all the results:
\[
6x^2 + 12x - 2x - 4
\]
Next, combine like terms (12x - 2x):
\[
6x^2 + 10x - 4
\]
Thus, the result of multiplying the polynomials (3x−1)(2x+4) is:
\[
6x^2 + 10x - 4
\]
So, the correct response is:
**6x² + 10x − 4**.
1. **First**: Multiply the first terms:
\(3x \cdot 2x = 6x^2\)
2. **Outer**: Multiply the outer terms:
\(3x \cdot 4 = 12x\)
3. **Inner**: Multiply the inner terms:
\(-1 \cdot 2x = -2x\)
4. **Last**: Multiply the last terms:
\(-1 \cdot 4 = -4\)
Now, we combine all the results:
\[
6x^2 + 12x - 2x - 4
\]
Next, combine like terms (12x - 2x):
\[
6x^2 + 10x - 4
\]
Thus, the result of multiplying the polynomials (3x−1)(2x+4) is:
\[
6x^2 + 10x - 4
\]
So, the correct response is:
**6x² + 10x − 4**.
