Solution for 9k^2-32k=0 equation:



9k^2-32k=0
a = 9; b = -32; c = 0;
Δ = b2-4ac
Δ = -322-4·9·0
Δ = 1024
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1024}=32$
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-32)-32}{2*9}=\frac{0}{18} =0 $
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-32)+32}{2*9}=\frac{64}{18} =3+5/9 $
