x = ±4

Step-by-step explanation:

3x^2 =48

Divide by 3

x^2 = 16

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4

Answer:

x = ± 4

Step-by-step explanation:

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

[tex]3x^2 = 48\\x^2 = 16[/tex]

Now take the square root of both sides:

[tex]\sqrt{x^2} =\sqrt{16} \\[/tex]

x = ± 4
