If you still up im really struggling

discriminant =0

1 real root

Step-by-step explanation:

The discriminant is b^2 -4ac  

when the equation is written in the form  ax^2 +bx+c

f(x) = 3x^2 +24x+48

a = 3   b = 24 and c =48

discriminant = 24^2 - 4(3)*(48)

                      =576-576

                        =0

If the discriminant >0  we have 2 real roots

if discriminant = 0  we have 1 real root

if discriminant <0 we have 2 complex roots
