3x^2+6x-6.5=0
a = 3; b = 6; c = -6.5;
Δ = b2-4ac
Δ = 62-4·3·(-6.5)
Δ = 114
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{-(6)-\sqrt{114}}{2*3}=\frac{-6-\sqrt{114}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+\sqrt{114}}{2*3}=\frac{-6+\sqrt{114}}{6} $
