We get rid of parentheses

114x^2+10x-9x=0

We add all the numbers together, and all the variables

114x^2+x=0

a = 114; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·114·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*114}=\frac{-2}{228}
=-1/114
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*114}=\frac{0}{228}
=0
