What are the solutions of x squared plus 121 equals 0?
Answer options with 4 options
A.
negative 11, 11
B.
11, 11 i
C.
11, negative 11 i
D.
negative 11 i, 11 i
The solutions of the equation x^2 + 121 = 0 can be found by taking the square root of both sides:
√(x^2 + 121) = ±√(-121)
Since the square root of a negative number is an imaginary number, we can rewrite the equation as:
x = ± 11i
Therefore, the correct answer is:
D. negative 11i, 11i
