4.7042615x^2-222518=0

a = 4.7042615; b = 0; c = -222518;
Δ = b2-4ac
Δ = 02-4·4.7042615·(-222518)
Δ = 4187131.441828
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{4187131.441828}}{2*4.7042615}=\frac{0-\sqrt{4187131.441828}}{9.408523}
=-\frac{\sqrt{}}{9.408523}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{4187131.441828}}{2*4.7042615}=\frac{0+\sqrt{4187131.441828}}{9.408523}
=\frac{\sqrt{}}{9.408523}
