Answer:

x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- [tex]\sqrt{-55}[/tex]

Simplify

x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Hope this helps!
