x^2-14x-375=0

Solution for x^2-14x-375=0 equation:

x^2-14x-375=0

a = 1; b = -14; c = -375;
Δ = b2-4ac
Δ = -142-4·1·(-375)
Δ = 1696
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:

$\sqrt{\Delta}=\sqrt{1696}=\sqrt{16*106}=\sqrt{16}*\sqrt{106}=4\sqrt{106}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-14)-4\sqrt{106}}{2*1}=\frac{14-4\sqrt{106}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-14)+4\sqrt{106}}{2*1}=\frac{14+4\sqrt{106}}{2}
