Solution for 7d^2+11d=0 equation: 



7d^2+11d=0

a = 7; b = 11; c = 0;
Δ = b2-4ac
Δ = 112-4·7·0
Δ = 121
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{121}=11$


$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(11)-11}{2*7}=\frac{-22}{14}
=-1+4/7
$


$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+11}{2*7}=\frac{0}{14}
=0
$
