3x²-9x+1+0 Find the discriminant

Sindrei [870]

Answer:

$\boxed{D = 69}$

Step-by-step explanation:

The given quadratic equation is:

$3x^2-9x+1 = 0$

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

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

Discriminant = b² - 4ac

D = (-9)²-4(3)(1)

D = 81 - 12

D = 69
