2n^2-13n-70=0
a = 2; b = -13; c = -70;
Δ = b2-4ac
Δ = -132-4·2·(-70)
Δ = 729
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{729}=27$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-27}{2*2}=\frac{-14}{4} =-3+1/2 $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+27}{2*2}=\frac{40}{4} =10 $
