Solution for d^2-26d=0 equation: 



d^2-26d=0

a = 1; b = -26; c = 0;
Δ = b2-4ac
Δ = -262-4·1·0
Δ = 676
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{676}=26$


$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-26)-26}{2*1}=\frac{0}{2}
=0
$


$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-26)+26}{2*1}=\frac{52}{2}
=26
$
