(x^2)=((12.2)^3)

Solution for (x^2)=((12.2)^3) equation:

(x^2)=((12.2)^3)

We move all terms to the left:

(x^2)-(((12.2)^3))=0

We add all the numbers together, and all the variables

x^2-1815.848=0

a = 1; b = 0; c = -1815.848;
Δ = b2-4ac
Δ = 02-4·1·(-1815.848)
Δ = 7263.392
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{7263.392}}{2*1}=\frac{0-\sqrt{7263.392}}{2}
=-\frac{\sqrt{}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{7263.392}}{2*1}=\frac{0+\sqrt{7263.392}}{2}
=\frac{\sqrt{}}{2}
