Question

The discriminant of the quadratic equation \(2x^2 - 4x + 3 = 0\)  is

(A) - 4

(B) 0

(C) - 8

(D) 8

Answer 1

Correct option is: (C) - 8  

\(2 x^2-4 x+3=0\)    

Comparing equation with \(a x^2+b x+c=0\)   

a = 2, b = -4, c = 3

We know that

\(D =b^2-4 a c \)

\(=(-4)^2-4 \times 2 \times 3 \)

\(=16-24 \)

= -8  

Answer 2

Correct option is: (C) - 8
