Thank you for the opportunity to help you with your question!

According to the question,

3(x^2) -1 =0

So, to solve it, we first add 1 to both sides of the equation. This gives

=> 3(x^2) -1 +1 = 1

=> 3(x^2) =1

Now, dividing both sides of the equation by 3 gives,

=> (x^2)= (1/3)

Now finally, taking the square root of both the sides gives,

=> x= + sqrt(1/3)

Hence, the value of x in + sqrt(1/3). This can also be written as x= + sqrt(3)/3.

Please let me know if you need any clarification. I'm always happy to answer your questions.
