We get rid of parentheses

126x^2+12x-3x=0

We add all the numbers together, and all the variables

126x^2+9x=0

a = 126; b = 9; c = 0;
Δ = b2-4ac
Δ = 92-4·126·0
Δ = 81
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{81}=9$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-9}{2*126}=\frac{-18}{252}
=-1/14
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+9}{2*126}=\frac{0}{252}
=0
