To find an expression equivalent to \(4x^3 + 8x^2 + 12x\) using the Distributive Property, we can factor out the greatest common factor from all the terms in the expression.

The terms in the expression are \(4x^3\), \(8x^2\), and \(12x\). The greatest common factor is \(4x\).

Now, we can factor out \(4x\):

\[
4x^3 + 8x^2 + 12x = 4x(x^2 + 2x + 3)
\]

Now that we have factored the original expression, we can check which of the given responses matches this.

The correct response from the options provided is:

**4x(x² + 2x + 3)**.

So, the answer is:

**4x(x² + 2x + 3)**.

Let's first simplify the expression \(4x^2 - 3x^2 + 5x - 24\).

1. Combine like terms for the \(x^2\) terms:
\[
4x^2 - 3x^2 = 1x^2 \quad \text{or} \quad x^2
\]

2. The expression now looks like:
\[
x^2 + 5x - 24
\]

Next, we can factor \(x^2 + 5x - 24\). We need to find two numbers that multiply to \(-24\) (the constant term) and add to \(5\) (the coefficient of \(x\)).

The numbers \(8\) and \(-3\) satisfy these conditions:
- \(8 \times -3 = -24\)
- \(8 + (-3) = 5\)

Therefore, we can factor the expression as:
\[
(x + 8)(x - 3)
\]

Now, let’s check which of the provided responses matches this factorization:

1. **(x + 8)(x - 3)** — This matches our factorization.
2. **4x(x - 6)** — This does not match.
3. **2(x - 12)** — This does not match.
4. **(x + 6)(x - 4)** — This does not match.

The expression \(4x^2 - 3x^2 + 5x - 24\) simplifies to \( (x + 8)(x - 3) \).

So, the answer is:
**(x + 8)(x - 3)**.

To add the polynomial expressions \(5z - 2z^2 - 4z + 5\) and \(6z^2 + 3 - 7z\), we will first combine the terms from both expressions.

1. Start by rewriting both expressions:
- The first expression: \(5z - 2z^2 - 4z + 5\)
- The second expression: \(6z^2 + 3 - 7z\)

2. Combine like terms from the first expression:
\[
5z - 4z = 1z \quad \text{so the first expression simplifies to} \quad -2z^2 + z + 5
\]

3. Now, rewrite the first expression with combined terms:
\[
-2z^2 + z + 5
\]

4. Now add the second expression:
\[
-2z^2 + z + 5 + 6z^2 + 3 - 7z
\]

5. Combine like terms:
- For \(z^2\) terms: \(-2z^2 + 6z^2 = 4z^2\)
- For \(z\) terms: \(z - 7z = -6z\)
- For the constant terms: \(5 + 3 = 8\)

6. Putting it all together:
\[
4z^2 - 6z + 8
\]

Now, we can look at your response choices:

- **4z² - 6z + 8** — This matches our calculation.
- **9z² - 11z + 8** — This does not match.
- **4z² - z + 8** — This does not match.
- **11z² + z - 2** — This does not match.

Thus, the answer is:
**4z² - 6z + 8**.

To simplify the expression \((9x^2 + 17x + 13) - (2x^2 + 12x + 11)\), we need to distribute the negative sign across the second polynomial and then combine like terms.

1. Start with the given expression:
\[
(9x^2 + 17x + 13) - (2x^2 + 12x + 11)
\]

2. Distributing the negative sign to the second polynomial:
\[
9x^2 + 17x + 13 - 2x^2 - 12x - 11
\]

3. Now, combine like terms:
- For the \(x^2\) terms: \(9x^2 - 2x^2 = 7x^2\)
- For the \(x\) terms: \(17x - 12x = 5x\)
- For the constant terms: \(13 - 11 = 2\)

4. Putting it all together, we have:
\[
7x^2 + 5x + 2
\]

Now, let's check the responses:

- **7x² + 29x + 24** — This does not match.
- **7x² + 5x + 2** — This matches our calculation.
- **9x² + 17x + 13 - 2x² - 12x - 11** — This represents the same expression but is not simplified.
- **12x² + 2** — This does not match.

Therefore, the correct answer is:
**7x² + 5x + 2**.

Answer 9

Bot GPT 4-o mini answered

To multiply the polynomials \( (3x - 1)(2x + 4) \), we can use the distributive property (also known as the FOIL method for binomials).

1. **First**: Multiply the first terms in each binomial:
\[
3x \cdot 2x = 6x^2
\]

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, combine all the results:
\[
6x^2 + 12x - 2x - 4
\]

Combine like terms:
\[
6x^2 + (12x - 2x) - 4 = 6x^2 + 10x - 4
\]

Now, we can write the final result as:
\[
6x^2 + 10x - 4
\]

So to fill in the blanks:
- \(x^2 + 10x - 4\)

Final answer:
\[
6x^2 + 10x - 4
\]

(Note: Since the formatting of the answer requested specifically "x^2 +", it seems you might want components separated, so it would fit as \(x^2 + 10x - 4\) accordingly).

Answer 11

To determine which of the given responses demonstrates that polynomials form a closed system under multiplication, we need to find an expression where the product of two polynomial expressions is also a polynomial.

**Analyzing each option:**

1. **\((x)(12x)\)**:
- The multiplication of \(x\) (a polynomial of degree 1) and \(12x\) (a polynomial of degree 1) results in \(12x^2\), which is also a polynomial.
- **This shows closure under multiplication.**

2. **\((\sqrt{x})(6x \cdot -3)\)**:
- \(\sqrt{x}\) is not a polynomial (it is a root) so this expression does not qualify as a polynomial multiplication and doesn't demonstrate closure under multiplication of polynomials.

3. **\(\frac{3x^2}{4} - 1\)**:
- This is a polynomial expression itself, but it is not a multiplication of two polynomials, so it does not demonstrate the closure property.

4. **\(14x^3 \cdot 5\)**:
- This multiplication results in \(70x^3\), which is a polynomial. However, because one of the factors is a constant (which is technically a polynomial of degree 0), this also shows closure.

**Conclusion:**
Both options 1 and 4 demonstrate closure under multiplication of polynomials, but option 1 (\((x)(12x)\)) is more straightforward as it consists purely of polynomials.

Thus, the response that clearly shows that polynomials form a closed system under multiplication is:
**\((x)(12x)\)**.
