[Algebra] Easiest way to solve this?

I have this formula 3x^(2) - 3 = 0
I know there are two answers for this, x = -1 and x = 1
I think I am missing some rule, or I am doing it wrong. What would be the most efficient or easiest way?
I divided by 3 -> x^(2) -1 = 0
Then moved the 1 to the right, or +1 both sides -> x^(2) = 1
And then I took the square root on both sides so x = √1
