Solution for 9m2+5m=0 equation: 



9m^2+5m=0

a = 9; b = 5; c = 0;
Δ = b2-4ac
Δ = 52-4·9·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$


$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-5}{2*9}=\frac{-10}{18}
=-5/9
$


$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+5}{2*9}=\frac{0}{18}
=0
