Simple....
you have:
So...first you know you're trying to find x..
But, you have a square root on one side...to remove this you'd have to square both sides--->>>
Leaving you with....
Move the terms over and set it equal to zero.
-->>
Factor out a 3...
What multiplies to -12 and adds to 4?
6*-2=-12
6+-2=4
Leaving you with...
Remember you're solving for 0....
3x-2=0
3x-2=0
+2 +2
3x=2
x=
Then-->>
x+2=0
x+2=0
-2 -2
x=-2
Thus, your answer.
