0.5x^2+10x+0.75=0
a = 0.5; b = 10; c = +0.75;
Δ = b2-4ac
Δ = 102-4·0.5·0.75
Δ = 98.5
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)-\sqrt{98.5}}{2*0.5}=\frac{-10-\sqrt{98.5}}{1} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+\sqrt{98.5}}{2*0.5}=\frac{-10+\sqrt{98.5}}{1} $
