h^2=224

Solution for h^2=224 equation:

h^2=224

We move all terms to the left:

h^2-(224)=0

a = 1; b = 0; c = -224;
Δ = b2-4ac
Δ = 02-4·1·(-224)
Δ = 896
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{896}=\sqrt{64*14}=\sqrt{64}*\sqrt{14}=8\sqrt{14}$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8\sqrt{14}}{2*1}=\frac{0-8\sqrt{14}}{2}
=-\frac{8\sqrt{14}}{2}
=-4\sqrt{14}
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8\sqrt{14}}{2*1}=\frac{0+8\sqrt{14}}{2}
=\frac{8\sqrt{14}}{2}
=4\sqrt{14}
