Both −6 and 6 make the equation x22=18 true. Use set notation to express these solutions. When entering your response, list elements in the set from least to greatest, with a comma between each element in the set.

Answer 1

The solutions to the equation \( x^2 = 18 \) are \( x = -6 \) and \( x = 6 \).

In set notation, this can be expressed as:

\[ {-6, 6} \]
