-0.5x^2+8x-9.3=0
a = -0.5; b = 8; c = -9.3;
Δ = b2-4ac
Δ = 82-4·(-0.5)·(-9.3)
Δ = 45.4
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{-(8)-\sqrt{45.4}}{2*-0.5}=\frac{-8-\sqrt{45.4}}{-1} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(8)+\sqrt{45.4}}{2*-0.5}=\frac{-8+\sqrt{45.4}}{-1} $
