3x squared= 6x-1
3x^2 - 6x + 1 = 0
- (- 6) +/- sqrt( (-6)^2 - 4*3*1) 6 +/- sqer(36 - 12)
x = ----------------------------------------- = ---------------------------
2*3 6
6 +/- sqrt(4*6) 6 +/- 2sqrt6
x = -------------------- = -------------------
6 6
x = ( 6 + 2sqrt6)/6 = (3 + sqrt6)/3 and
x = (6 - 2sqrt6)/6 = ( 3 - sqrt6)/3
