Solution for 0.555555555555556x^2=8 equation:

0.555555555555556x^2=8

We move all terms to the left:

0.555555555555556x^2-(8)=0

a = 0.555555555555556; b = 0; c = -8;
Δ = b2-4ac
Δ = 02-4·0.555555555555556·(-8)
Δ = 17.777777777778
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{17.777777777778}}{2*0.555555555555556}=\frac{0-\sqrt{17.777777777778}}{1.1111111111111}
=-\frac{\sqrt{}}{1.1111111111111}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{17.777777777778}}{2*0.555555555555556}=\frac{0+\sqrt{17.777777777778}}{1.1111111111111}
=\frac{\sqrt{}}{1.1111111111111}
