x^2-27x+139=0
a = 1; b = -27; c = +139;
Δ = b2-4ac
Δ = -272-4·1·139
Δ = 173
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{-(-27)-\sqrt{173}}{2*1}=\frac{27-\sqrt{173}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-27)+\sqrt{173}}{2*1}=\frac{27+\sqrt{173}}{2} $
