To solve the equation \( x^2 = 196 \) using inspection, we can look for numbers that, when squared, equal 196.
We can compute:
- \( 14^2 = 196 \)
- \( (-14)^2 = 196 \)
Both \( 14 \) and \( -14 \) satisfy the equation.
Thus, the solution set is:
\({-14, 14}\)
So the correct response is:
\({-14, 14}\)
