## Step 1: Understanding the Discriminant

The discriminant of a quadratic equation $ ax^2 + bx + c =  $ is given by the formula:
$$
D = b^2 - 4ac
$$
The value of the discriminant determines the nature of the roots of the quadratic equation.

## Step 2: Analyzing the Negative Discriminant

When the discriminant ($ D $) is negative ($ D <  $), the expression under the square root in the quadratic formula:
$$
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
$$
becomes negative. The square root of a negative number is not a real number, but rather an imaginary number. This means the roots will not be real, but instead will be complex numbers.

## Step 3: Identifying the Type of Complex Roots

For quadratic equations with a negative discriminant, the roots are of the form:
$$
x = \frac{-b \pm i\sqrt{|b^2 - 4ac|}}{2a}
$$
where $ i $ is the imaginary unit ($ i^2 = -1 $). These roots are always complex conjugates of each other, meaning they are of the form $ a + bi $ and $ a - bi $.

## Final Answer

**C) Complex conjugates**

---

**Explanation Recap:**
1. The discriminant determines the nature of quadratic roots.
2. A negative discriminant means the square root is imaginary, so roots are not real.
3. Such roots are always complex conjugates of each other.
