You can put this solution on YOUR website!
Given 3x^2 - 2x + 1 = 0
If eqn is ax^2 + bx + c = 0, then
x+=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29
Here a = 3, b = -2, c = 1
Plugging in these values in the formula,
x=%282%2B-sqrt%284-12%29%29%2F6
==>x=%282%2B-sqrt%28-8%29%29%2F6
==>x=%281%2B-sqrt%28-2%29%29%2F3 [dividing by 2 throughout]
==> x=%281%2B-sqrt%28-2%29%29%2F3

Good luck!!!
