find the discriminate of quadratic equation 4x2-2/3 x -1/16=0

On comparing with the general equation , we get

  • 11
4X2-2/3X-1/16=0
(192X2-32X-3)/48=0
192X2-32X-3=0
AX2+BX+C=0
D=B2-4AC
=(-32)2-4*192*-3
1024+2304=3328
ANS=3328
  • -5

4 x 2 - 2/3x - 1/16  =  0 

Here , a = 4  b  = -2/3  c = -1/16

Discriminant  d = b2 - 4ac

substituting the values

  =  (-2/3) -  4 (4)(-1/16)

  =  4/9  - ( - 1)

  =  4/9 + 1

  =  13/9
