Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website!
The discriminant for a quadratic equation is given by
when the equation is in the form
.
.
.
Rearrange the equation,
In your case,
The discriminant is then,
.
.
.
The discriminant gives you information regarding the roots depending on its value.
If , you have two distinct real roots.
If , you have two coincident real roots.
If , you have two complex roots (complex conjugates).
.
.
.
Since , you will have two complex conjugate roots.
