-16x^2+96x-116=0

Solution for -16x^2+96x-116=0 equation:

-16x^2+96x-116=0

a = -16; b = 96; c = -116;
Δ = b2-4ac
Δ = 962-4·(-16)·(-116)
Δ = 1792
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:

$\sqrt{\Delta}=\sqrt{1792}=\sqrt{256*7}=\sqrt{256}*\sqrt{7}=16\sqrt{7}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(96)-16\sqrt{7}}{2*-16}=\frac{-96-16\sqrt{7}}{-32}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(96)+16\sqrt{7}}{2*-16}=\frac{-96+16\sqrt{7}}{-32}
