Question

x^2=-9

Answer 1

To solve you would take the square root of both sides, but you can not take the square root of a negative number. So there's no solution

Answer 2

but if your subject require you to find the complex root you can also solve this

Answer 3

its just it has no Real number solution root , but theres complex root,
do you want me to show you?

Answer 4

yes

Answer 5

remember \[\sqrt{-1}=i\]

Answer 6

x^2=-9 square root on both sides gives
\[x=\sqrt{-9}\]
\[x=\sqrt{9(-1)}\]
\[x=+9 i and x=-3 i\]

Answer 7

im sorry thats x= plus or minus 3 i

Answer 8

x= 3 i, x= -3 i
thats your complex roots
