x^2-5x-8.07=0
a = 1; b = -5; c = -8.07;
Δ = b2-4ac
Δ = -52-4·1·(-8.07)
Δ = 57.28
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{-(-5)-\sqrt{57.28}}{2*1}=\frac{5-\sqrt{57.28}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+\sqrt{57.28}}{2*1}=\frac{5+\sqrt{57.28}}{2} $
