Answer:

[tex]\boxed{D = 69}[/tex]

Step-by-step explanation:

The given quadratic equation is:

[tex]3x^2-9x+1 = 0[/tex]

Comparing it with the standard form of Quadratic Equation [tex]ax^2+bx+c = 0[/tex] , we get:

a = 3, b = -9 and c = 1

Discriminant = b² - 4ac

D = (-9)²-4(3)(1)

D = 81 - 12

D = 69
