Wy multiply elements

6x^2-326x+1=0

a = 6; b = -326; c = +1;
Δ = b2-4ac
Δ = -3262-4·6·1
Δ = 106252
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{106252}=\sqrt{4*26563}=\sqrt{4}*\sqrt{26563}=2\sqrt{26563}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-326)-2\sqrt{26563}}{2*6}=\frac{326-2\sqrt{26563}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-326)+2\sqrt{26563}}{2*6}=\frac{326+2\sqrt{26563}}{12}
