How many real roots does the equation 2x² + 4x + 5 = 0 have?
Correct answer: A. No real roots
- A. No real roots
- B. One real root
- C. Two equal real roots
- D. Two distinct real roots
Explanation
The discriminant is b² - 4ac = 4² - 4(2)(5) = -24. Since the discriminant is negative, the equation has no real roots.
