The first step is to add 48 to each side, so you are left with 3x2 = 48

then, divide each side by 3

you should now have x= 16

If you take the square root of both, you will get plus or minus 4.

The positive value of x is 4.

=> 3x^2=48




so, x=4 , or -x=4 => x=-4

but, as only positive values of x are required, x≠-4

ANS. x=4.
