if so then just use foil or box technique to multiply (3x -1) against itself to get

9x^2 -6x +1 = 2

subtract 2 from both side to get

9x^2 - 6x -1 = 0

and then use quadratic formula to solve for x because i dont think you can factor this unless missing something

or, with less work,

(3x-1)^2 = 2

3x-1 = ±√2

3x = 1±√2

x = (1±√2)/3
