Question

Las raíces de la ecuación ─3x2

+ 9 = 0 son
​

Answer 1

Respuesta:

X1 = ✓108 ÷ 6

X2 = -✓108 ÷ 6

Explicación paso a paso:

$3 {x}^{2} - 9 = 0$

a = 3

b = 0

C = -9

X= [-b ± ✓ (b²-4ac)] ÷ (2a)

X1 = [-b + ✓ (b²-4ac)] ÷ (2a)

X1 = {0 + ✓ [-4(3)(-9)] } ÷ (6)

X1 = ✓108 ÷ 6

X2 = [-b - ✓ (b²-4ac)] ÷ (2a)

X2 = {0 - ✓ [-4(3)(-9)] } ÷ (6)

X2 = -✓108 ÷ 6
