Solution for 40z2-32z=0 equation:



40z^2-32z=0
a = 40; b = -32; c = 0;
Δ = b2-4ac
Δ = -322-4·40·0
Δ = 1024
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$z_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$z_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1024}=32$
$z_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-32)-32}{2*40}=\frac{0}{80} =0 $
$z_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-32)+32}{2*40}=\frac{64}{80} =4/5 $
