X2+9 =0

=> X2 = -9

=> X = ±√(-9) = ±3i

Answer 2

$\mathfrak \red{given : {x}^{2} + 9 = 0 } \\ \mathfrak \red{too \: find : value \: of \: x} \\ \mathfrak \green{solve : } \\ \mathfrak \green{ {x}^{2} + 9 = 0 } \\ \mathfrak \green{ {x}^{2} = - 9} \\ \mathfrak \green{x = \frac{ + }{} \sqrt{ - 9} } \\ \mathfrak \green{x = \frac{ + }{}( - 3) } \\ \mathfrak \green{ \boxed{x = - 3 \: or \: + 3}}$
