Solution for X*y=116.5 equation:

X*X=116.5

We move all terms to the left:

X*X-(116.5)=0

We add all the numbers together, and all the variables

X*X-116.5=0

Wy multiply elements

X^2-116.5=0

a = 1; b = 0; c = -116.5;
Δ = b2-4ac
Δ = 02-4·1·(-116.5)
Δ = 466
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{466}}{2*1}=\frac{0-\sqrt{466}}{2}
=-\frac{\sqrt{}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{466}}{2*1}=\frac{0+\sqrt{466}}{2}
=\frac{\sqrt{}}{2}
