Solution for .6x2+3x=0 equation: 



.6x^2+3x=0

a = .6; b = 3; c = 0;
Δ = b2-4ac
Δ = 32-4·.6·0
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

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


$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-3}{2*.6}=\frac{-6}{1.2}
=-5
$


$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+3}{2*.6}=\frac{0}{1.2}
=0
$
