1.117x^2+128x+35=0
a = 1.117; b = 128; c = +35;
Δ = b2-4ac
Δ = 1282-4·1.117·35
Δ = 16227.62
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{-(128)-\sqrt{16227.62}}{2*1.117}=\frac{-128-\sqrt{16227.62}}{2.234} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(128)+\sqrt{16227.62}}{2*1.117}=\frac{-128+\sqrt{16227.62}}{2.234} $
