x^2+0.01272x-0.00110677=0

a = 1; b = 0.01272; c = -0.00110677;
Δ = b2-4ac
Δ = 0.012722-4·1·(-0.00110677)
Δ = 0.0045888784
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0.01272)-\sqrt{0.0045888784}}{2*1}=\frac{-0.01272-\sqrt{0.0045888784}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0.01272)+\sqrt{0.0045888784}}{2*1}=\frac{-0.01272+\sqrt{0.0045888784}}{2}
