What is the value of the discriminant, b2 − 4ac, for the quadratic equation 0 = x2 − 4x + 5, and what does it mean about the number of real solutions the equation has?

The discriminant is −4, so the equation has 2 real solutions.
The discriminant is −4, so the equation has no real solutions.
The discriminant is 35, so the equation has 2 real solutions.
The discriminant is 35, so the equation has no real solutions.

The correct option is B because the discriminant is , so the equation has no real solutions.

Given:

The equation is:

To find:

The discriminant of the given equation.

Explanation:

In a quadratic equation , the discriminant is:

If , then the equation has 2 real solutions.

If , then the equation has 1 real solution.

If , then the equation has no real solutions.

In the given equation, we have .

Since , therefore the equation has no real solutions.

Hence, the correct option is B.
