Question

F(x)=-4x^2+10x-8

what is the value of the discriminant of F


How many distinct real number zeros dose f have

Answer 1

Explanation:

a = - 4

b = 10

c = - 8

The discriminate is

D = b^2 - 4ac

D = 10^2 - 4*(-4)(-8)

D = 100 - 128

D = - 28 which is not a nice number

Because the Discriminate has a minus result, there are no real zeros.
