Solution for -8n^2+11n+2=0 equation: 



-8n^2+11n+2=0

a = -8; b = 11; c = +2;
Δ = b2-4ac
Δ = 112-4·(-8)·2
Δ = 185
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{-(11)-\sqrt{185}}{2*-8}=\frac{-11-\sqrt{185}}{-16}
$


$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+\sqrt{185}}{2*-8}=\frac{-11+\sqrt{185}}{-16}
$
