We calculate fractions


(2x+1)/8x^2+20x/8x^2-4-2=0

We add all the numbers together, and all the variables

(2x+1)/8x^2+20x/8x^2-6=0

We multiply all the terms by the denominator


(2x+1)+20x-6*8x^2=0

We add all the numbers together, and all the variables

20x+(2x+1)-6*8x^2=0

Wy multiply elements

-48x^2+20x+(2x+1)=0

We get rid of parentheses

-48x^2+20x+2x+1=0

We add all the numbers together, and all the variables

-48x^2+22x+1=0

a = -48; b = 22; c = +1;
Δ = b2-4ac
Δ = 222-4·(-48)·1
Δ = 676
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{676}=26$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(22)-26}{2*-48}=\frac{-48}{-96}
=1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(22)+26}{2*-48}=\frac{4}{-96}
=-1/24
