-16x^2+96x+80=0

Solution for -16x^2+96x+80=0 equation:

-16x^2+96x+80=0

a = -16; b = 96; c = +80;
Δ = b2-4ac
Δ = 962-4·(-16)·80
Δ = 14336
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:

$\sqrt{\Delta}=\sqrt{14336}=\sqrt{1024*14}=\sqrt{1024}*\sqrt{14}=32\sqrt{14}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(96)-32\sqrt{14}}{2*-16}=\frac{-96-32\sqrt{14}}{-32}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(96)+32\sqrt{14}}{2*-16}=\frac{-96+32\sqrt{14}}{-32}
