5x^2-10.4x+0.5=0
a = 5; b = -10.4; c = +0.5;
Δ = b2-4ac
Δ = -10.42-4·5·0.5
Δ = 98.16
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{-(-10.4)-\sqrt{98.16}}{2*5}=\frac{10.4-\sqrt{98.16}}{10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10.4)+\sqrt{98.16}}{2*5}=\frac{10.4+\sqrt{98.16}}{10} $
