Answer:
[tex]x=-2i\sqrt{3} , 2i\sqrt{3}[/tex]
Step-by-step explanation:
The equation is already set equal to zero, so that is a good start
We then need to get x by itself. To do so we need to subtract 12 from both sides to get x² = -12
Then we need to take the square root of both sides[tex]\sqrt{x^{2} } =\sqrt{-12}[/tex] which gives us [tex]x=-2i\sqrt{3} , 2i\sqrt{3}[/tex]
