15.1790=6.5h2

Solution for 15.1790=6.5h2 equation:

15.1790=6.5h^2

We move all terms to the left:

15.1790-(6.5h^2)=0

We add all the numbers together, and all the variables

-(6.5h^2)+15.179=0

We get rid of parentheses

-6.5h^2+15.179=0

a = -6.5; b = 0; c = +15.179;
Δ = b2-4ac
Δ = 02-4·(-6.5)·15.179
Δ = 394.654
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{394.654}}{2*-6.5}=\frac{0-\sqrt{394.654}}{-13}
=-\frac{\sqrt{}}{-13}
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{394.654}}{2*-6.5}=\frac{0+\sqrt{394.654}}{-13}
=\frac{\sqrt{}}{-13}
