Question

Which would be the best method to use to solve the following equation. Explain your reasoning.

Answer 1

Answer:

x = ±8

Step-by-step explanation:

The given equation is :

$3x^2-192=0$

We can use the Square root Property to solve it.

Adding 192 both sides,

$3x^2-192=0\\\\3x^2=192$

Dividing both sides by 3.

$x^2=64\\\\x=\sqrt{64} \\\\x=\pm 8$

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