Answer:

A and B

Step-by-step explanation:

We can add 48 to both sides of the equation to get

3x^2 = 48

Dividing by 3 on both sides,

x^2 = 16

Taking the square root of both sides,

x = +/- 4

So A and B are our answers.

Answer: Option A and Option B

[tex]x=4[/tex] and [tex]x=-4[/tex]

Step-by-step explanation:

We must find the solutions of the following equation

[tex]3x^2-48=0[/tex]

Add 48 on both sides of the equality

[tex]3x^2-48+48=48[/tex]

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

Divide both sides of equality by 3

[tex]\frac{3}{3}x^2=\frac{48}{3}[/tex]

[tex]x^2=16[/tex]

Apply the square root on both sides of the equation

[tex]x=\±\sqrt{16}[/tex]

[tex]x=4[/tex] and [tex]x=-4[/tex]
