0.5x^2-5x-10.5=0
a = 0.5; b = -5; c = -10.5;
Δ = b2-4ac
Δ = -52-4·0.5·(-10.5)
Δ = 46
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{46}}{2*0.5}=\frac{5-\sqrt{46}}{1} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+\sqrt{46}}{2*0.5}=\frac{5+\sqrt{46}}{1} $
