To determine which equations have the solution set {14, -5}, we analyze each provided equation to see what values of \( x \) would satisfy them.
1. **(8x - 2)(x + 5) = 0**
- Solutions: \( 8x - 2 = 0 \) gives \( x = \frac{2}{8} = \frac{1}{4} \).
- \( x + 5 = 0 \) gives \( x = -5 \).
- Solutions are {−5, 0.25}, so this equation does not work.
2. **(x + 14)(x + 5) = 0**
- Solutions: \( x + 14 = 0 \) gives \( x = -14 \).
- \( x + 5 = 0 \) gives \( x = -5 \).
- Solutions are {−14, −5}, so this equation does not work.
3. **(x − 14)(x − 5) = 0**
- Solutions: \( x - 14 = 0 \) gives \( x = 14 \).
- \( x - 5 = 0 \) gives \( x = 5 \).
- Solutions are {14, 5}, so this equation does not work.
4. **(2x - 8)(x - 5) = 0**
- Solutions: \( 2x - 8 = 0 \) gives \( x = 4 \).
- \( x - 5 = 0 \) gives \( x = 5 \).
- Solutions are {4, 5}, so this equation does not work.
5. **(4x − 1)(x + 5) = 0**
- Solutions: \( 4x - 1 = 0 \) gives \( x = \frac{1}{4} \).
- \( x + 5 = 0 \) gives \( x = -5 \).
- Solutions are {−5, 0.25}, so this equation does not work.
6. **(x − 14)(x + 5) = 0**
- Solutions: \( x - 14 = 0 \) gives \( x = 14 \).
- \( x + 5 = 0 \) gives \( x = -5 \).
- Solutions are {14, -5}, so this equation works.
7. **(4x + 2)(x + 5) = 0**
- Solutions: \( 4x + 2 = 0 \) gives \( x = -\frac{1}{2} \).
- \( x + 5 = 0 \) gives \( x = -5 \).
- Solutions are {−5, -0.5}, so this equation does not work.
Based on this analysis, the equation that satisfies the solution set {14, −5} is:
- **(x − 14)(x + 5) = 0**
