What is the principal solution to the equation? x^2=121

Pls explain for brainliest and a like
1.step by step
2. correct answer
3. clearly explained

x = 11

Step-by-step explanation:

= 121

This means that 'x' × 'x' = 121

To know the value of x, we need to find the root of 121.

= 11

If u mutiply 11 x 11 , you get 121.

Thus, x = 11

x = 11, -11

use the formula:    ➳  

changing the sides, changes square ( ² ) to square root ( ±√ )

there is no graph so i cant sorry
