a = 3
b = -4
c = 1
hence,
x = (4 ± √16-12)/6
x = (4 ± 2)/6
x = (4+2)/6 or x = (4-2)/6
x = 1 or x = 1/3

Answer -4 + 2 = -2/6 = -1/3
Answer -4 - 2 = -6/6 = -1

0 = 3x² - 4x + 1
x = [ -b ± â ( (b)² - 4(a)(c) ) ] / 2(a)
x = [ -(-4) ± â ( (-4)² - 4(3)(1) ) ] / 2(3)
x = [ 4 ± â ( 16 - 12 ) ] / 6
x = [ 4 ± â4 ] / 6
x = [ 4 ± 2 ] / 6
x = (4 - 2) / 6 or (4 + 2) / 6
x = { 1/3, 1 }
