Question

Question find the discriminant of the quadratic equation 3 x square - 6 x minus 4 is equal to zero and hence find the nature of the roots

Answer 1

Answer:

3x²-6x-4=0

a=3,b= -6,c= -4

D=b²-4ac

( -6)² - 4(3)( -4)

36+48

84

thereforeD=84

Answer 2

The discriminant   is 84

nature of roots are  irrational and unequal

Step-by-step explanation:

given quadratic equation

3x² -6x-4

here a= 3

b = -6

c= -4

then

discriminant  = b²-4ac

=(-6)² - 4 ×3×(-4)

= 36 +48

= 84

The discriminant   is 84

since the value of discriminant is greater than zero it has real roots

i.e

b²-4ac  >0

therefore ,discriminant = 84 , which is not a perfect square

hence , nature of roots are  irrational and unequal
