3x2 – 6x + 4 = 0

A.
one real-number root

B.
no real-number roots

C.
two real-number roots

D.
three real-number roots
@perl , can you please help?

Answer 1

the discriminant tells us about the roots of the equation (the solutions of the equation).

if the discriminant is positive , then there are 2 real-number roots
if discriminant is zero , there is one real-number root.
if discriminant is negative, there are 2 non-real roots

Answer 2

use the same formula :)
