6u^2-10u+1=0

Solution for 6u^2-10u+1=0 equation:

6u^2-10u+1=0

a = 6; b = -10; c = +1;
Δ = b2-4ac
Δ = -102-4·6·1
Δ = 76
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{76}=\sqrt{4*19}=\sqrt{4}*\sqrt{19}=2\sqrt{19}$
$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-10)-2\sqrt{19}}{2*6}=\frac{10-2\sqrt{19}}{12}
$
$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10)+2\sqrt{19}}{2*6}=\frac{10+2\sqrt{19}}{12}
