Question

3X ao quadrado menos 12 igual a zero

Answer 1

$x^{2} = \frac{12}{3}$

$3 x^{2} - 12 = 0$

$x = \sqrt{4 }$

X= 2 

Answer 2

3x²-12=0

 Onde:

A=3

B=-12

C=0

Vamos Achar delta:

Δ=b²-4*a*c

Δ=(-12)²-4*3*0

Δ=144

X=-b+-√Δ/2*a

X1=-(-12)+√144/2*3 = 12+12/2*3  = 24/6 = 4

X2=-(-12)-√144/2*3  = 12-12/6 = 0/6  = 0
