Solution for 80d^2-5d=0 equation: 



80d^2-5d=0

a = 80; b = -5; c = 0;
Δ = b2-4ac
Δ = -52-4·80·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$


$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-5)-5}{2*80}=\frac{0}{160}
=0
$


$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+5}{2*80}=\frac{10}{160}
=1/16
$
