x2-25x-2200=0

Solution for x2-25x-2200=0 equation:

x2-25x-2200=0

We add all the numbers together, and all the variables

x^2-25x-2200=0

a = 1; b = -25; c = -2200;
Δ = b2-4ac
Δ = -252-4·1·(-2200)
Δ = 9425
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:

$\sqrt{\Delta}=\sqrt{9425}=\sqrt{25*377}=\sqrt{25}*\sqrt{377}=5\sqrt{377}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-25)-5\sqrt{377}}{2*1}=\frac{25-5\sqrt{377}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-25)+5\sqrt{377}}{2*1}=\frac{25+5\sqrt{377}}{2}
