4x2+24x+4=0

Solution for 4x2+24x+4=0 equation:

4x^2+24x+4=0

a = 4; b = 24; c = +4;
Δ = b2-4ac
Δ = 242-4·4·4
Δ = 512
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:

$\sqrt{\Delta}=\sqrt{512}=\sqrt{256*2}=\sqrt{256}*\sqrt{2}=16\sqrt{2}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-16\sqrt{2}}{2*4}=\frac{-24-16\sqrt{2}}{8}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+16\sqrt{2}}{2*4}=\frac{-24+16\sqrt{2}}{8}
