c2=1,728

Solution for c2=1,728 equation:

c2=1.728

We move all terms to the left:

c2-(1.728)=0

We add all the numbers together, and all the variables

c^2-1.728=0

a = 1; b = 0; c = -1.728;
Δ = b2-4ac
Δ = 02-4·1·(-1.728)
Δ = 6.912
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{6.912}}{2*1}=\frac{0-\sqrt{6.912}}{2}
=-\frac{\sqrt{}}{2}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{6.912}}{2*1}=\frac{0+\sqrt{6.912}}{2}
=\frac{\sqrt{}}{2}
