Answer:

x = ± 4

Explanation:

You need to get
x^2 by itself, and to do this, you divide both sides by 3, like so:


3x^2 = 48\\x^2 = 16

Now take the square root of both sides:


√(x^2) =√(16) \\

x = ± 4

Answer:

x = ±4

Explanation:

3x^2 =48

Divide by 3

3x^2/3 = 48/3

x^2 = 16

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4
