3x2=182-12=0

Solution for 3x2=182-12=0 equation:

3x^2=182-12=0

We move all terms to the left:

3x^2-(182-12)=0

We add all the numbers together, and all the variables

3x^2-170=0

a = 3; b = 0; c = -170;
Δ = b2-4ac
Δ = 02-4·3·(-170)
Δ = 2040
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:

$\sqrt{\Delta}=\sqrt{2040}=\sqrt{4*510}=\sqrt{4}*\sqrt{510}=2\sqrt{510}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{510}}{2*3}=\frac{0-2\sqrt{510}}{6}
=-\frac{2\sqrt{510}}{6}
=-\frac{\sqrt{510}}{3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{510}}{2*3}=\frac{0+2\sqrt{510}}{6}
=\frac{2\sqrt{510}}{6}
=\frac{\sqrt{510}}{3}
