Answer:
C
Step-by-step explanation:
The nature of the solutions are determined by the value of the discriminant.
Given a quadratic equation in standard form ax² + bx + c = 0 : a ≠ 0
Then the discriminant is Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then solutions are real and equal
• If b² - 4ac < 0 then solutions are not real, 2 complex conjugate solutions
Here b² - 4ac = - 6 , hence 2 complex conjugate solutions → C
