The discriminant value of a quadratic equation ax² + bx + c = 0, a ≠ 0 is given by,

D = b² - 4ac = 0

i. If D = b² - 4ac > 0, then its roots are distinct and real.

ii. If D = b² - 4ac = 0, then its roots are real and equal.

iii. If D = b² - 4ac < 0, then its roots are imaginary.

Given,

∴ D = b² - 4ac = 0

= -3 < 0

Hence, the roots of the quadratic equation are imaginary.
