To solve the equation (x−18)² = 196, we can take the square root of both sides:
√((x−18)²) = √196
This simplifies to:
x−18 = ±14
Now, we can add 18 to both sides to isolate x:
x = 18 ± 14
So the solutions to the quadratic equation are:
x = 18 + 14 = 32
x = 18 - 14 = 4
Therefore, the correct answer is {32, 4}.
