To solve the equation \( x^2 - 121 = 0 \), you can first add 121 to both sides of the equation:
\[
x^2 = 121
\]
Next, take the square root of both sides:
\[
x = \pm \sqrt{121}
\]
Since \( \sqrt{121} = 11 \), we find:
\[
x = 11 \quad \text{or} \quad x = -11
\]
Since the problem asks for the lesser number first, the final answer is:
\[
x = -11, \quad x = 11
\]
\[
x^2 = 121
\]
Next, take the square root of both sides:
\[
x = \pm \sqrt{121}
\]
Since \( \sqrt{121} = 11 \), we find:
\[
x = 11 \quad \text{or} \quad x = -11
\]
Since the problem asks for the lesser number first, the final answer is:
\[
x = -11, \quad x = 11
\]
