70n^2+56n=0
a = 70; b = 56; c = 0;
Δ = b2-4ac
Δ = 562-4·70·0
Δ = 3136
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{3136}=56$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(56)-56}{2*70}=\frac{-112}{140} =-4/5 $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(56)+56}{2*70}=\frac{0}{140} =0 $
