Domain of the equation: 8h!=0

h!=0/8

h!=0

h∈R



Domain of the equation: 4h!=0

h!=0/4

h!=0

h∈R


We calculate fractions


4h/32h^2+(-24h)/32h^2+7=0

We multiply all the terms by the denominator


4h+(-24h)+7*32h^2=0

Wy multiply elements

224h^2+4h+(-24h)=0

We get rid of parentheses

224h^2+4h-24h=0

We add all the numbers together, and all the variables

224h^2-20h=0

a = 224; b = -20; c = 0;
Δ = b2-4ac
Δ = -202-4·224·0
Δ = 400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{400}=20$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-20)-20}{2*224}=\frac{0}{448}
=0
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-20)+20}{2*224}=\frac{40}{448}
=5/56
