Solution for 0,5*x^2+4x=0 equation:



0.5x^2+4x=0
a = 0.5; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·0.5·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*0.5}=\frac{-8}{1} =-8 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*0.5}=\frac{0}{1} =0 $
