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

We add all the numbers together, and all the variables

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

We multiply all the terms by the denominator


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

Wy multiply elements

-24x^2+4x+(-2x)=0

We get rid of parentheses

-24x^2+4x-2x=0

We add all the numbers together, and all the variables

-24x^2+2x=0

a = -24; b = 2; c = 0;
Δ = b2-4ac
Δ = 22-4·(-24)·0
Δ = 4
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4}=2$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2}{2*-24}=\frac{-4}{-48}
=1/12
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2}{2*-24}=\frac{0}{-48}
=0
