A) real, rational, and unequal
B) real, irrational, and unequal
C) real, rational, and equal
D) imaginary

Respuesta :

Answer:

b

Step-by-step explanation:

Since the given discriminant is 10, hence the roots will be real, irrational, and unequal

Discriminant of an equation

The discriminant is used to determine the nature of the roots of a quadratic equation. The formula for finding the discriminant is expressed as:

D = b^2 - 4ac

  • If D > 0, the nature of the roots are real, irrational, and unequal
  • If D <  0, the nature of the roots are imaginary

Since the given discriminant is 10, hence the roots will be real, irrational, and unequal
