Question

Resolvendo a equação x² - 6x + 9 = 0, obtemos:
x = 3
x = 2
x = 6
x = -3​

Answer 1

a=1

b=-6

c=9

Δ= b² - 4ac

Δ = -6² - 4 × 1 × 9

Δ = 36 - 36

Δ =0

6 + 0/ 2= 3

6 - 0/2 =3

Answer 2

꧁Hello, how are you?꧂

$x {}^{2} - 6x + 9 = 0 \\ (x - 3) {}^{2} = 0 \\ x - 3 = 0 \\ x - 3 + 3 = 0 + 3 \\ x = 0 + 3 \\ x = 3$
