h*h=11.5

Solution for h*h=11.5 equation:

h*h=11.5

We move all terms to the left:

h*h-(11.5)=0

We add all the numbers together, and all the variables

h*h-11.5=0

Wy multiply elements

h^2-11.5=0

a = 1; b = 0; c = -11.5;
Δ = b2-4ac
Δ = 02-4·1·(-11.5)
Δ = 46
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{46}}{2*1}=\frac{0-\sqrt{46}}{2}
=-\frac{\sqrt{}}{2}
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{46}}{2*1}=\frac{0+\sqrt{46}}{2}
=\frac{\sqrt{}}{2}
