Let's solve each quadratic equation to find its solution set:
1. **2x² − 32 = 0**
- 2x² = 32
- x² = 16
- x = ±4
- Solution set: {-4, 4}
2. **4x² − 100 = 0**
- 4x² = 100
- x² = 25
- x = ±5
- Solution set: {-5, 5}
3. **x² − 55 = 9**
- x² = 64
- x = ±8
- Solution set: {-8, 8}
4. **x² − 140 = -19**
- x² = 121
- x = ±11
- Solution set: {-11, 11}
5. **2x² − 18 = 0**
- 2x² = 18
- x² = 9
- x = ±3
- Solution set: {-3, 3} (not listed in your options, so we ignore)
Now we can match the equations with their solution sets:
1. **2x² − 32 = 0** -> {-4, 4}
2. **4x² − 100 = 0** -> {-5, 5}
3. **x² − 55 = 9** -> {-8, 8}
4. **x² − 140 = -19** -> {-11, 11}
So the completed pairs are:
- **2x² − 32 = 0** ↔ **{-4, 4}**
- **4x² − 100 = 0** ↔ **{-5, 5}**
- **x² − 55 = 9** ↔ **{-8, 8}**
- **x² − 140 = -19** ↔ **{-11, 11}**
The tile "2x² − 18 = 0" is not matched because its solution set is not provided.
1. **2x² − 32 = 0**
- 2x² = 32
- x² = 16
- x = ±4
- Solution set: {-4, 4}
2. **4x² − 100 = 0**
- 4x² = 100
- x² = 25
- x = ±5
- Solution set: {-5, 5}
3. **x² − 55 = 9**
- x² = 64
- x = ±8
- Solution set: {-8, 8}
4. **x² − 140 = -19**
- x² = 121
- x = ±11
- Solution set: {-11, 11}
5. **2x² − 18 = 0**
- 2x² = 18
- x² = 9
- x = ±3
- Solution set: {-3, 3} (not listed in your options, so we ignore)
Now we can match the equations with their solution sets:
1. **2x² − 32 = 0** -> {-4, 4}
2. **4x² − 100 = 0** -> {-5, 5}
3. **x² − 55 = 9** -> {-8, 8}
4. **x² − 140 = -19** -> {-11, 11}
So the completed pairs are:
- **2x² − 32 = 0** ↔ **{-4, 4}**
- **4x² − 100 = 0** ↔ **{-5, 5}**
- **x² − 55 = 9** ↔ **{-8, 8}**
- **x² − 140 = -19** ↔ **{-11, 11}**
The tile "2x² − 18 = 0" is not matched because its solution set is not provided.
