340=6x^2

Solution for 340=6x^2 equation:

340=6x^2

We move all terms to the left:

340-(6x^2)=0

a = -6; b = 0; c = +340;
Δ = b2-4ac
Δ = 02-4·(-6)·340
Δ = 8160
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:

$\sqrt{\Delta}=\sqrt{8160}=\sqrt{16*510}=\sqrt{16}*\sqrt{510}=4\sqrt{510}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{510}}{2*-6}=\frac{0-4\sqrt{510}}{-12}
=-\frac{4\sqrt{510}}{-12}
=-\frac{\sqrt{510}}{-3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{510}}{2*-6}=\frac{0+4\sqrt{510}}{-12}
=\frac{4\sqrt{510}}{-12}
=\frac{\sqrt{510}}{-3}
