Answer 1

To divide the polynomial \( 4x^2 + 4x - 10 \) by \( 2x - 3 \), we will use polynomial long division.

1. **Divide the leading term of the numerator by the leading term of the denominator**:
\[
\frac{4x^2}{2x} = 2x
\]

2. **Multiply the entire divisor by this result**:
\[
2x(2x - 3) = 4x^2 - 6x
\]

3. **Subtract this from the original polynomial**:
\[
(4x^2 + 4x - 10) - (4x^2 - 6x) = 4x + 6x - 10 = 10x - 10
\]

4. **Now, divide the leading term of the new polynomial by the leading term of the divisor**:
\[
\frac{10x}{2x} = 5
\]

5. **Multiply the entire divisor by this result**:
\[
5(2x - 3) = 10x - 15
\]

6. **Subtract this from the polynomial**:
\[
(10x - 10) - (10x - 15) = -10 + 15 = 5
\]

At this point, we have finished our division process. The quotient is \( 2x + 5 \) and the remainder is \( 5 \).

Thus, the answer is:
- The quotient is \( 2x + 5 \).
- The remainder is \( 5 \).

So the correct response is:
**The quotient is 2x + 5. The remainder is 5.**
