-0.5q^2+6q+12.5=0
a = -0.5; b = 6; c = +12.5;
Δ = b2-4ac
Δ = 62-4·(-0.5)·12.5
Δ = 61
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$q_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$q_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$q_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-\sqrt{61}}{2*-0.5}=\frac{-6-\sqrt{61}}{-1} $$q_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+\sqrt{61}}{2*-0.5}=\frac{-6+\sqrt{61}}{-1} $
