Solution for 8x2=24 equation:



8x^2=24
We move all terms to the left:
8x^2-(24)=0
a = 8; b = 0; c = -24;
Δ = b2-4ac
Δ = 02-4·8·(-24)
Δ = 768
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:
$\sqrt{\Delta}=\sqrt{768}=\sqrt{256*3}=\sqrt{256}*\sqrt{3}=16\sqrt{3}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-16\sqrt{3}}{2*8}=\frac{0-16\sqrt{3}}{16} =-\frac{16\sqrt{3}}{16} =-\sqrt{3} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+16\sqrt{3}}{2*8}=\frac{0+16\sqrt{3}}{16} =\frac{16\sqrt{3}}{16} =\sqrt{3} $
