4x/8x^2+(-22x)/8x^2-3-2=0

We add all the numbers together, and all the variables

4x/8x^2+(-22x)/8x^2-5=0

We multiply all the terms by the denominator


4x+(-22x)-5*8x^2=0

Wy multiply elements

-40x^2+4x+(-22x)=0

We get rid of parentheses

-40x^2+4x-22x=0

We add all the numbers together, and all the variables

-40x^2-18x=0

a = -40; b = -18; c = 0;
Δ = b2-4ac
Δ = -182-4·(-40)·0
Δ = 324
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{324}=18$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-18}{2*-40}=\frac{0}{-80}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+18}{2*-40}=\frac{36}{-80}
=-9/20
