4x^2+4x-92=0

Solution for 4x^2+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}
