4.9t^2-17t+3.5=0
a = 4.9; b = -17; c = +3.5;
Δ = b2-4ac
Δ = -172-4·4.9·3.5
Δ = 220.4
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{-(-17)-\sqrt{220.4}}{2*4.9}=\frac{17-\sqrt{220.4}}{9.8} $$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-17)+\sqrt{220.4}}{2*4.9}=\frac{17+\sqrt{220.4}}{9.8} $
