x²=121

To solve the equation x² = 121, we need to determine the value of x.

To do this, we can take the square root of both sides of the equation:

√(x²) = √121

Simplifying, we have:

|x| = 11

Now, we know that the square root of a number can have both a positive and a negative value. Therefore, we have two possibilities for the value of x:

1. x = 11
2. x = -11

So, the equation x² = 121 has two solutions: x = 11 and x = -11.
