x^2-44x-126=0

Solution for x^2-44x-126=0 equation:

x^2-44x-126=0

a = 1; b = -44; c = -126;
Δ = b2-4ac
Δ = -442-4·1·(-126)
Δ = 2440
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:

$\sqrt{\Delta}=\sqrt{2440}=\sqrt{4*610}=\sqrt{4}*\sqrt{610}=2\sqrt{610}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-44)-2\sqrt{610}}{2*1}=\frac{44-2\sqrt{610}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-44)+2\sqrt{610}}{2*1}=\frac{44+2\sqrt{610}}{2}
