Assuming you mean x^2 = 900, here are two standard symbolic methods.

Method 1 — square root:
1. x^2 = 900
2. x = ±√900 (taking the square root of both sides)
3. x = ±30

Method 2 — factoring:
1. x^2 = 900 ⇒ x^2 − 900 = 0
2. x^2 − 900 = (x − 30)(x + 30)
3. (x − 30)(x + 30) = 0 ⇒ x − 30 = 0 or x + 30 = 0
4. x = 30 or x = −30

Check by substitution: 30^2 = 900 and (−30)^2 = 900.
