We add all the numbers together, and all the variables

-234x^2+12x=0

a = -234; b = 12; c = 0;
Δ = b2-4ac
Δ = 122-4·(-234)·0
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{144}=12$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(12)-12}{2*-234}=\frac{-24}{-468}
=2/39
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+12}{2*-234}=\frac{0}{-468}
=0
