If the discriminant of a quadratic equation is equal to -8, there are two complex roots.
<h3>Discriminant of a quadratic equation</h3>
The discriminant is used to determine the nature of quadratic equations.
The formula for calculating discriminant is given as:
D = b^2 - 4ac
If the discriminant is negative, it means that the nature of the solution will be a complex number.
Hence if the discriminant of a quadratic equation is equal to -8, there are two complex roots.
