Question

What is the value of the discriminant, b2-4ac, for the quadratic equation 0=x^2-4x+5, and what does it mean about the number of real solutions the equation has

Answer 1

Answer:

-4, no real solutions

Step-by-step explanation:

b^2 is 16 since b is -4

4ac = 4*1*5 = 20

16 - 20 is -4

no real solutions since you cant get the squareroot out of a negative number (at least not real numbers)
