Let's solve each quadratic equation to find its solution set:
-
2x² − 32 = 0
- 2x² = 32
- x² = 16
- x = ±4
- Solution set: {-4, 4}
-
4x² − 100 = 0
- 4x² = 100
- x² = 25
- x = ±5
- Solution set: {-5, 5}
-
x² − 55 = 9
- x² = 64
- x = ±8
- Solution set: {-8, 8}
-
x² − 140 = -19
- x² = 121
- x = ±11
- Solution set: {-11, 11}
-
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:
- 2x² − 32 = 0 -> {-4, 4}
- 4x² − 100 = 0 -> {-5, 5}
- x² − 55 = 9 -> {-8, 8}
- 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.
