4*3x^2-6=0

Wy multiply elements

12x^2-6=0

a = 12; b = 0; c = -6;
Δ = b2-4ac
Δ = 02-4·12·(-6)
Δ = 288
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:

$\sqrt{\Delta}=\sqrt{288}=\sqrt{144*2}=\sqrt{144}*\sqrt{2}=12\sqrt{2}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{2}}{2*12}=\frac{0-12\sqrt{2}}{24}
=-\frac{12\sqrt{2}}{24}
=-\frac{\sqrt{2}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{2}}{2*12}=\frac{0+12\sqrt{2}}{24}
=\frac{12\sqrt{2}}{24}
=\frac{\sqrt{2}}{2}
