Answer 2

x = √3

x = - √3

Explanation:

x^2 - 3 = 0 Add 3 to both sides

x^2 = 3 Take the square root of both sides.

sqrt(x^2) = sqrt(3)

x = +/- sqrt(3)

Remember that the - root is also a solution to the question. Also for this question don't put the - sign under the root sign. That is an entirely different question.
