9.18x^2+2x-5.5=0
a = 9.18; b = 2; c = -5.5;
Δ = b2-4ac
Δ = 22-4·9.18·(-5.5)
Δ = 205.96
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{-(2)-\sqrt{205.96}}{2*9.18}=\frac{-2-\sqrt{205.96}}{18.36} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+\sqrt{205.96}}{2*9.18}=\frac{-2+\sqrt{205.96}}{18.36} $
