$\sin (2 x) = - \frac{\sqrt{2}}{2}$

Step 1

Add $\frac{\sqrt{2}}{2}$ to both sides of the equation.

$\sin (2 x) + \frac{\sqrt{2}}{2} = 0$

Step 2

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
