x^2+130x+-3000=0

Solution for x^2+130x+-3000=0 equation:

x^2+130x+-3000=0

We add all the numbers together, and all the variables

x^2+130x=0

a = 1; b = 130; c = 0;
Δ = b2-4ac
Δ = 1302-4·1·0
Δ = 16900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16900}=130$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(130)-130}{2*1}=\frac{-260}{2}
=-130
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(130)+130}{2*1}=\frac{0}{2}
=0
