Solution for 12x^2-2x-4= equation:

12x^2-2x-4=

We move all terms to the left:

12x^2-2x-4-()=0

We add all the numbers together, and all the variables

12x^2-2x=0

a = 12; b = -2; c = 0;
Δ = b2-4ac
Δ = -22-4·12·0
Δ = 4
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4}=2$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-2}{2*12}=\frac{0}{24}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+2}{2*12}=\frac{4}{24}
=1/6
