Solution for 18a^2+4a=0 equation: 



18a^2+4a=0

a = 18; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·18·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$


$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*18}=\frac{-8}{36}
=-2/9
$


$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*18}=\frac{0}{36}
=0
$
