7n^2-23n-8=0
a = 7; b = -23; c = -8;
Δ = b2-4ac
Δ = -232-4·7·(-8)
Δ = 753
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}$$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-23)-\sqrt{753}}{2*7}=\frac{23-\sqrt{753}}{14} $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-23)+\sqrt{753}}{2*7}=\frac{23+\sqrt{753}}{14} $
