C
Correct answer
Explanation
Solving x^2 + 3 = 0 leads to x^2 = -3. Taking the square root of both sides gives x = +/- sqrt(-3), which is +/- i*sqrt(3).
AI explanation
We isolate the variable in the equation x squared plus 3 equals 0 to get x squared equals negative 3. Taking the square root of both sides yields x equals the square root of negative 3. Using the identity for complex numbers where the square root of negative 1 is i, we get x equals plus or minus i times the square root of 3.
