Question

AYUDEN POR FAVOR DOY CORONA ::calcule la discriminante de la ecuación :)
${ \times }^{2} - 6 \times + 9 = 0$

​

Answer 1

x=2a−b+−b2−4ac​​

Para:

x² - 6x + 9 = 0

a = 1

b = -6

c = 9

Entonces:

x=2(1)6+−(−6)2−4(1)(9)​​

x = \{6+-\{36-36}}{2}x=26+−36−36​​

x = \{6+-\{0}}{2}x=26+−0​​

x = \{6+-0}{2}x=26+−0​

\ x = {6}{2} x=26​

x = 3

Answer 2

Discriminante de x^2 - 6x + 9 = 0.

Δ = ((-6)^2 - 4 × 1 × 9)^(1/2)

Δ = (0)^(1/2)

Es decir, el discriminate es cero.
