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."
