5n^2+16n-16=0
a = 5; b = 16; c = -16;
Δ = b2-4ac
Δ = 162-4·5·(-16)
Δ = 576
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{576}=24$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(16)-24}{2*5}=\frac{-40}{10} =-4 $
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(16)+24}{2*5}=\frac{8}{10} =4/5 $
