Question

which does not describe the equation
$\sqrt{x = - 2}$
​

Answer 1

Answer:

which of what ?

and the equation is not right. I don't know what you mean.

do you mean x = sqrt(-2) ?

all I can tell you just based on that assumption is that you can transform that into

$x = \sqrt{2} \times i$

you know,

$i = \sqrt{ - 1}$

but what else you might need is completely unclear.
