Answer:
Step-by-step explanation:
2x^2 - 32 = 0
Solution Set: {-4, 4}
4x^2 - 100 = 0
Solution Set: {-5, 5}
x^2 - 55 = 9
Solution Set: {-11, 11}
x^2 - 140 = -19
Solution Set: {-8, 8}
So, the matches are as follows:
The solution to the first equation is {-4, 4}.
The solution to the second equation is {-5, 5}.
The solution to the third equation is {-11, 11}.
The solution to the fourth equation is {-8, 8}.
