what is the value of the discriminant, b2 ā 4ac, for the quadratic equation 0 = x2 ā 4x 5, and what does it mean about the number of real solutions the equation has?
d = b^2 - 4ac, where a = 1, b = -4, c = 5 d = (-4)^2 - 4 x 1 x 5 d = 16 - 20 d = -4 Since d is negative, this means that there is no real solution to the equation.
