Find Delta first and then compute results.

#### Explanation:

Yur equation is
$2 {x}^{2} - 2 x + 1 = 0$

when you arrange your original equation. Now you can compute Delta:

$\Delta = {b}^{2} - 4 a c$ (where b=-2, a=2 and c=1].

$\Delta = 4 - 8 = - 4$

If Delta is negative there is no solution (in real numbers)
