Solution for 20x2+44x=0 equation:



20x^2+44x=0
a = 20; b = 44; c = 0;
Δ = b2-4ac
Δ = 442-4·20·0
Δ = 1936
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1936}=44$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(44)-44}{2*20}=\frac{-88}{40} =-2+1/5 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(44)+44}{2*20}=\frac{0}{40} =0 $
