Discriminant of standard quadratic equation 

ax2 + bx + c = 0 is b2 – 4ac 

Now comparing the given quadratic equation 2x2 – 4x + 3 = 0 with standard form of quadratic equation. 

We get a = 2, b = -4, c = 3 then its discriminant = b2 – 4ac 

= (-4)2 – 4(2) (3)

= 16 – 24 = -8 

∴ Discriminant = -8.
