Solution for X^2+128x=0 equation: 



X^2+128X=0

a = 1; b = 128; c = 0;
Δ = b2-4ac
Δ = 1282-4·1·0
Δ = 16384
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16384}=128$


$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(128)-128}{2*1}=\frac{-256}{2}
=-128
$


$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(128)+128}{2*1}=\frac{0}{2}
=0
