x^2-50x-11400=0

Solution for x^2-50x-11400=0 equation:

x^2-50x-11400=0

a = 1; b = -50; c = -11400;
Δ = b2-4ac
Δ = -502-4·1·(-11400)
Δ = 48100
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:

$\sqrt{\Delta}=\sqrt{48100}=\sqrt{100*481}=\sqrt{100}*\sqrt{481}=10\sqrt{481}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-50)-10\sqrt{481}}{2*1}=\frac{50-10\sqrt{481}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-50)+10\sqrt{481}}{2*1}=\frac{50+10\sqrt{481}}{2}
