x squared - i = 0

$\displaystyle x^2-i=0$

$\displaystyle x^2=i$

$\displaystyle x=\sqrt{i}$

$\displaystyle x=\sqrt{\sqrt-1}$

$\displaystyle x=\pm(\frac{1+i}{\sqrt2})$

What symbol(s) is(are) needed to make Delimiters (. . .) bigger to completely encompass fraction?

Either you can just choose bigger ones, like \big( and \big), or \Big( and \Big), or \Big[ and \Big].
Or you can use pairs of \left( and \right) or \left[ and \right] that will be resized automatically to the height of the expression that is contained in them, like this

$\displaystyle x=\pm\left(\frac{1+i}{\sqrt{2}}\right)^2$
