I take it you mean √(3x-2) +2 = 0 and not something like
√(3x) - 2 +2 = 0

Get the radical by itself, then square both sides to get rid of the radical. Then solve for x.

√(3x-2) +2 = 0
√(3x-2) = -2
3x - 2 = 4
I'm sure you can take it from there

â(3x-2) +2 = 0 subtract 2 from each side
â(3x-2)=-2 square both sides
3x-2=4 add 2 to each side
3x=6 divide both sides by 3
x=2

check
â(2*2-2)+2=0
â4+2=0

There is no solution!
