9t+12.5t^2-1=0
a = 12.5; b = 9; c = -1;
Δ = b2-4ac
Δ = 92-4·12.5·(-1)
Δ = 131
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{-(9)-\sqrt{131}}{2*12.5}=\frac{-9-\sqrt{131}}{25} $$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{131}}{2*12.5}=\frac{-9+\sqrt{131}}{25} $
