Which quadratic equation has no real solutions?
A) 3X² - 3 = 0
B) 3X² + 3X = 0
C) 3X² + 3X + 3 = 0
D) 3X² - 6X + 3 = 0
Solution
Correct answer: C) 3X² + 3X + 3 = 0.
This equation has a discriminant (b² - 4ac) that is negative, which means the equation has no real roots.
The discriminant for this equation is:
b² - 4ac = (3)² −4 (3) (3) = 9 − 36 = −27
Since the discriminant is negative, this quadratic equation has no real solutions.
