Question

Find the discriminant of the equation 3x² – 2x + 1/3 = 0 and hence find the nature of its roots. Find them, if they are real.

Answer 1

Answer:

Roots are real and equal.

Step-by-step explanation:

Compare given Quadratic equation

with ax² + bx + c = 0 ,we get

a = 3 , b = -2 , c = 1/3 ,

Discreminant ( D ) = b² - 4ac

= ( -2 )² - 4 × 3 × ( 1/3 )

= 4 - 4

= 0

Therefore ,

Roots are real and equal.

Answer 2

Answer:

Roots are equal and real..

Step-by-step explanation:

By comparing with quadratic equation

ax2+bx+c=0

a=3,b=-2,c=1/3

Discriminant (D)= b^2 -4ac

=(-2)^2-4×3×1/3

=4-4×3×1/3

=4-4=0
