26s^2+9s=0

a = 26; b = 9; c = 0;
Δ = b2-4ac
Δ = 92-4·26·0
Δ = 81
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{81}=9$


$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-9}{2*26}=\frac{-18}{52}
=-9/26
$


$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+9}{2*26}=\frac{0}{52}
=0
