Solution for 9w^2+3w=0 equation: 



9w^2+3w=0

a = 9; b = 3; c = 0;
Δ = b2-4ac
Δ = 32-4·9·0
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$


$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-3}{2*9}=\frac{-6}{18}
=-1/3
$


$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+3}{2*9}=\frac{0}{18}
=0
$
