196=s2

Solution for 196=s2 equation:

196=s2

We move all terms to the left:

196-(s2)=0

We add all the numbers together, and all the variables

-1s^2+196=0

a = -1; b = 0; c = +196;
Δ = b2-4ac
Δ = 02-4·(-1)·196
Δ = 784
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{784}=28$
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-28}{2*-1}=\frac{-28}{-2}
=+14
$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+28}{2*-1}=\frac{28}{-2}
=-14
