2x^2-2x-96=0

Solution for 2x^2-2x-96=0 equation:

2x^2-2x-96=0

a = 2; b = -2; c = -96;
Δ = b2-4ac
Δ = -22-4·2·(-96)
Δ = 772
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:

$\sqrt{\Delta}=\sqrt{772}=\sqrt{4*193}=\sqrt{4}*\sqrt{193}=2\sqrt{193}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-2\sqrt{193}}{2*2}=\frac{2-2\sqrt{193}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+2\sqrt{193}}{2*2}=\frac{2+2\sqrt{193}}{4}
