\[
(x^2 + 9x + 17) \div (x + 4)
\]
#### Solution:
Perform polynomial long division:
1. Divide the leading term of the numerator (\(x^2\)) by the leading term of the denominator (\(x\)):
\[
\frac{x^2}{x} = x
\]
Write \(x\) above the division bar.
2. Multiply \(x\) by \(x + 4\):
\[
x \cdot (x + 4) = x^2 + 4x
\]
Subtract this from the original polynomial:
\[
(x^2 + 9x + 17) - (x^2 + 4x) = 5x + 17
\]
3. Divide the leading term of the new polynomial (\(5x\)) by the leading term of the denominator (\(x\)):
\[
\frac{5x}{x} = 5
\]
Write \(5\) above the division bar.
4. Multiply \(5\) by \(x + 4\):
\[
5 \cdot (x + 4) = 5x + 20
\]
Subtract this from the current polynomial:
\[
(5x + 17) - (5x + 20) = -3
\]
The quotient is \(x + 5\) and the remainder is \(-3\). Thus:
\[
x + 5 - \frac{3}{x + 4}
\]
Answer:
\[
\boxed{x + 5 - \frac{3}{x + 4}}
\]
---
\[
(x^2 - x - 16) \div (x - 4)
\]
#### Solution:

\[
\frac{x^2}{x} = x
\]
Write \(x\) above the division bar.
2. Multiply \(x\) by \(x - 4\):
\[
x \cdot (x - 4) = x^2 - 4x
\]
Subtract this from the original polynomial:
\[
(x^2 - x - 16) - (x^2 - 4x) = 3x - 16
\]
3. Divide the leading term of the new polynomial (\(3x\)) by the leading term of the denominator (\(x\)):
\[
\frac{3x}{x} = 3
\]
Write \(3\) above the division bar.
4. Multiply \(3\) by \(x - 4\):
\[
3 \cdot (x - 4) = 3x - 12
\]
Subtract this from the current polynomial:
\[
(3x - 16) - (3x - 12) = -4
\]
The quotient is \(x + 3\) and the remainder is \(-4\). Thus:
\[
x + 3 - \frac{4}{x - 4}
\]
Answer:
\[
\boxed{x + 3 - \frac{4}{x - 4}}
\]
---
\[

\[
\frac{x^2}{x} = x
\]
Write \(x\) above the division bar.
2. Multiply \(x\) by \(x - 1\):
\[
x \cdot (x - 1) = x^2 - x
\]
Subtract this from the original polynomial:
\[
(x^2 - 6x + 2) - (x^2 - x) = -5x + 2
\]
3. Divide the leading term of the new polynomial (\(-5x\)) by the leading term of the denominator (\(x\)):
\[
\frac{-5x}{x} = -5
\]
Write \(-5\) above the division bar.
4. Multiply \(-5\) by \(x - 1\):
\[
-5 \cdot (x - 1) = -5x + 5
\]
Subtract this from the current polynomial:
\[
(-5x + 2) - (-5x + 5) = -3
\]
The quotient is \(x - 5\) and the remainder is \(-3\). Thus:
\[
x - 5 - \frac{3}{x - 1}
\]
Answer:
\[
\boxed{x - 5 - \frac{3}{x - 1}}
\]
---
\[
(x^2 - x - 24) \div (x - 5)

\[
4 \cdot (x - 5) = 4x - 20
\]
Subtract this from the current polynomial:
\[
(4x - 24) - (4x - 20) = -4
\]
The quotient is \(x + 4\) and the remainder is \(-4\). Thus:
\[
x + 4 - \frac{4}{x - 5}
\]
Answer:
\[
\boxed{x + 4 - \frac{4}{x - 5}}
