2h^2=262

Solution for 2h^2=262 equation:

2h^2=262

We move all terms to the left:

2h^2-(262)=0

a = 2; b = 0; c = -262;
Δ = b2-4ac
Δ = 02-4·2·(-262)
Δ = 2096
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:

$\sqrt{\Delta}=\sqrt{2096}=\sqrt{16*131}=\sqrt{16}*\sqrt{131}=4\sqrt{131}$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{131}}{2*2}=\frac{0-4\sqrt{131}}{4}
=-\frac{4\sqrt{131}}{4}
=-\sqrt{131}
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{131}}{2*2}=\frac{0+4\sqrt{131}}{4}
=\frac{4\sqrt{131}}{4}
=\sqrt{131}
