230=10h*5h

Solution for 230=10h*5h equation:

230=10h*5h

We move all terms to the left:

230-(10h*5h)=0

We add all the numbers together, and all the variables

-(+10h*5h)+230=0

We get rid of parentheses

-10h*5h+230=0

Wy multiply elements

-50h^2+230=0

a = -50; b = 0; c = +230;
Δ = b2-4ac
Δ = 02-4·(-50)·230
Δ = 46000
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:

$\sqrt{\Delta}=\sqrt{46000}=\sqrt{400*115}=\sqrt{400}*\sqrt{115}=20\sqrt{115}$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-20\sqrt{115}}{2*-50}=\frac{0-20\sqrt{115}}{-100}
=-\frac{20\sqrt{115}}{-100}
=-\frac{\sqrt{115}}{-5}
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+20\sqrt{115}}{2*-50}=\frac{0+20\sqrt{115}}{-100}
=\frac{20\sqrt{115}}{-100}
=\frac{\sqrt{115}}{-5}
