Solution for 4x2-4x-92=0 equation:



4x^2-4x-92=0
a = 4; b = -4; c = -92;
Δ = b2-4ac
Δ = -42-4·4·(-92)
Δ = 1488
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:
$\sqrt{\Delta}=\sqrt{1488}=\sqrt{16*93}=\sqrt{16}*\sqrt{93}=4\sqrt{93}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4)-4\sqrt{93}}{2*4}=\frac{4-4\sqrt{93}}{8} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4)+4\sqrt{93}}{2*4}=\frac{4+4\sqrt{93}}{8} $
