x^2-900-339000=0

Solution for x^2-900-339000=0 equation:

x^2-900-339000=0

We add all the numbers together, and all the variables

x^2-339900=0

a = 1; b = 0; c = -339900;
Δ = b2-4ac
Δ = 02-4·1·(-339900)
Δ = 1359600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1359600}=\sqrt{400*3399}=\sqrt{400}*\sqrt{3399}=20\sqrt{3399}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-20\sqrt{3399}}{2*1}=\frac{0-20\sqrt{3399}}{2}
=-\frac{20\sqrt{3399}}{2}
=-10\sqrt{3399}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+20\sqrt{3399}}{2*1}=\frac{0+20\sqrt{3399}}{2}
=\frac{20\sqrt{3399}}{2}
=10\sqrt{3399}
