Why:

Respuesta :

Answer:

x = ±8

Step-by-step explanation:

The given equation is :

[tex]3x^2-192=0[/tex]

We can use the Square root Property to solve it.

Adding 192 both sides,

[tex]3x^2-192=0\\\\3x^2=192[/tex]

Dividing both sides by 3.

[tex]x^2=64\\\\x=\sqrt{64} \\\\x=\pm 8[/tex]

So, the value of x is equal to +8 and -8.
