X²=121

To solve the equation x² = 121, you need to find the values of x that satisfy the equation.

Taking the square root of both sides of the equation, we have:

√(x²) = √121

Simplifying, we get:

|x| = 11

This means that x can be either positive or negative 11. Therefore, the solutions to the equation x² = 121 are x = 11 and x = -11.
