70t^2-165t-135=0
a = 70; b = -165; c = -135;
Δ = b2-4ac
Δ = -1652-4·70·(-135)
Δ = 65025
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}$$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{65025}=255$$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-165)-255}{2*70}=\frac{-90}{140} =-9/14 $$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-165)+255}{2*70}=\frac{420}{140} =3 $
