160=c2

Solution for 160=c2 equation:

160=c2

We move all terms to the left:

160-(c2)=0

We add all the numbers together, and all the variables

-1c^2+160=0

a = -1; b = 0; c = +160;
Δ = b2-4ac
Δ = 02-4·(-1)·160
Δ = 640
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{640}=\sqrt{64*10}=\sqrt{64}*\sqrt{10}=8\sqrt{10}$
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8\sqrt{10}}{2*-1}=\frac{0-8\sqrt{10}}{-2}
=-\frac{8\sqrt{10}}{-2}
=-\frac{4\sqrt{10}}{-1}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8\sqrt{10}}{2*-1}=\frac{0+8\sqrt{10}}{-2}
=\frac{8\sqrt{10}}{-2}
=\frac{4\sqrt{10}}{-1}
