8.8t^2-15.5t-60=0
a = 8.8; b = -15.5; c = -60;
Δ = b2-4ac
Δ = -15.52-4·8.8·(-60)
Δ = 2352.25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-15.5)-\sqrt{2352.25}}{2*8.8}=\frac{15.5-\sqrt{2352.25}}{17.6} $$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-15.5)+\sqrt{2352.25}}{2*8.8}=\frac{15.5+\sqrt{2352.25}}{17.6} $
