-0,008x^2+0,36x=0

Solution for -0,008x^2+0,36x=0 equation:

-0.008x^2+0.36x=0

a = -0.008; b = 0.36; c = 0;
Δ = b2-4ac
Δ = 0.362-4·(-0.008)·0
Δ = 0.1296
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0.36)-\sqrt{0.1296}}{2*-0.008}=\frac{-0.36-\sqrt{0.1296}}{-0.016}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0.36)+\sqrt{0.1296}}{2*-0.008}=\frac{-0.36+\sqrt{0.1296}}{-0.016}
