x^2-39x+70=0
a = 1; b = -39; c = +70;
Δ = b2-4ac
Δ = -392-4·1·70
Δ = 1241
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{-(-39)-\sqrt{1241}}{2*1}=\frac{39-\sqrt{1241}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-39)+\sqrt{1241}}{2*1}=\frac{39+\sqrt{1241}}{2} $
