Answer:

The value of x is 2 or -2.

Step-by-step explanation:

Consider the provided equation.

[tex]3x^2= 12[/tex]

We need to solve the above equation for x.

Divide 3 from both the sides.

[tex]\frac{3x^2}{3}=\frac{12}{3}[/tex]

[tex]x^2=4[/tex]

Square root both the sides.

[tex]x=\pm \sqrt{4}[/tex]

[tex]x=\pm 2[/tex]

Hence the value of x is 2 or -2.
