a. two real, rational roots
b. two real, irrational roots
c. one real, double root
d. two complex roots

Option D. two complex roots

Step-by-step explanation:

we know that

In a quadratic equation of the form the discriminant D is equal to

in this problem we have

so

substitute the values

The discriminant is negative

therefore

The quadratic equation has two complex roots
