6x2-2x=19

Solution for 6x2-2x=19 equation:

6x^2-2x=19

We move all terms to the left:

6x^2-2x-(19)=0

a = 6; b = -2; c = -19;
Δ = b2-4ac
Δ = -22-4·6·(-19)
Δ = 460
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:

$\sqrt{\Delta}=\sqrt{460}=\sqrt{4*115}=\sqrt{4}*\sqrt{115}=2\sqrt{115}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-2\sqrt{115}}{2*6}=\frac{2-2\sqrt{115}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+2\sqrt{115}}{2*6}=\frac{2+2\sqrt{115}}{12}
