Solution for 2z2+20z=0 equation: 



2z^2+20z=0

a = 2; b = 20; c = 0;
Δ = b2-4ac
Δ = 202-4·2·0
Δ = 400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$z_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$z_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{400}=20$


$z_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(20)-20}{2*2}=\frac{-40}{4}
=-10
$


$z_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(20)+20}{2*2}=\frac{0}{4}
=0
$
