Solve for x:

x^2+120=0

A. - 11, - 11i

B. - 11, 11i

C. 11, 11i

D. 11, - 11i

None of the above

Step-by-step explanation:

x^2+120=0 can be rewritten as x^2 = - 120. Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or

x = plus or minus i*2√30

So the correct answer choice here is "None of the above."
