When solving, at what point do you know that your solutions are imaginary? Does x^2 +9 =0 have real or imaginary solutions? How do you know?

x^2=-9
x= root of negative 9
this means the answer is imaginary because a root of a number CAN’T be negative, which makes root of negative 9 an imaginary number therefore we call it an imaginary answer
