2x^2-19x+19=0
a = 2; b = -19; c = +19;
Δ = b2-4ac
Δ = -192-4·2·19
Δ = 209
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{-(-19)-\sqrt{209}}{2*2}=\frac{19-\sqrt{209}}{4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-19)+\sqrt{209}}{2*2}=\frac{19+\sqrt{209}}{4} $
