The quadratic equation 2x² - 4x + 12 = 0 has

A. 2 distinct real roots
B. no real roots
C. 2 equal real roots
D. more than 2 real roots

Answer: The quadratic equation 2x² - 4x + 12 = 0 has no real roots.

Let us check the nature of roots using the discriminant formula.

Explanation:

The nature of roots of the given equation can be given by,

D = b² - 4ac = 0 for a quadratic equation ax² + bx + c = 0

In the given quadratic equation 2x² - 4x + 12 = 0, a = 2 b = -4 and c = 12

Substituting the values in D = b² - 4ac we get,

D = (-4)² - (4)(2)(12) = 16 - 96 = -80 < 0

Since D is negative, it has no real roots.

Hence, option B i.e. no real root is the correct option.
