Find the discriminant of the quadratic equation 2x2-4x+3=0 and hence find the nature of its roots

The given quadratic equation is 2x- 4x + 3 = 0
we have a = 2  ;  b = -4  ;  c = 3
D = b2 - 4ac = (-4)2 - 4(2)(3) = 16 - 24 = -8

Since, D < 0 , so the given equation has no real roots.

2x2 - 4x + 3 = 0

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

D = b2 - 4ac

= (-4)2 - 4(2)(3)

= 16 - 24

= -8

The discriminant of the quad. eq. is -8.

Since D

  • 3

Since D is less than 0, therefore the roots of the given eq. are not real.
