x2+2x-4623=0

Solution for x2+2x-4623=0 equation:

x2+2x-4623=0

We add all the numbers together, and all the variables

x^2+2x-4623=0

a = 1; b = 2; c = -4623;
Δ = b2-4ac
Δ = 22-4·1·(-4623)
Δ = 18496
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{18496}=136$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-136}{2*1}=\frac{-138}{2}
=-69
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+136}{2*1}=\frac{134}{2}
=67
