356=s2

Solution for 356=s2 equation:

356=s2

We move all terms to the left:

356-(s2)=0

We add all the numbers together, and all the variables

-1s^2+356=0

a = -1; b = 0; c = +356;
Δ = b2-4ac
Δ = 02-4·(-1)·356
Δ = 1424
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1424}=\sqrt{16*89}=\sqrt{16}*\sqrt{89}=4\sqrt{89}$
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{89}}{2*-1}=\frac{0-4\sqrt{89}}{-2}
=-\frac{4\sqrt{89}}{-2}
=-\frac{2\sqrt{89}}{-1}
$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{89}}{2*-1}=\frac{0+4\sqrt{89}}{-2}
=\frac{4\sqrt{89}}{-2}
=\frac{2\sqrt{89}}{-1}
