Question

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?

Answer 1

Answer: The discriminant is −4, so the equation has no real solutions

Step-by-step explanation:

Answer 2

in your problem a = 1, b = -4 and c = 5
so discriminant is -4
the discriminat is the value under the radical so if the number is negative there is no real solution.
if the number is 0 there is one solution
if the number is positive there are two solutions
