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.
